    .SYNOPSIS
        Assert that required parameters has been specified.

    .DESCRIPTION
        Assert that required parameters has been specified, and throws an exception if not.

    .PARAMETER BoundParameterList
       A hashtable containing the parameters to evaluate. Normally this is set to
       $PSBoundParameters.

    .PARAMETER RequiredParameter
       One or more parameter names that is required to have been specified.

    .PARAMETER IfParameterPresent
       One or more parameter names that if specified will trigger the evaluation.
       If neither of the parameter names has been specified the evaluation of required
       parameters are not made.

    .EXAMPLE
        Assert-RequiredCommandParameter -BoundParameter $PSBoundParameters -RequiredParameter @('PBStartPortRange', 'PBEndPortRange')

        Throws an exception if either of the two parameters are not specified.

    .EXAMPLE
        Assert-RequiredCommandParameter -BoundParameter $PSBoundParameters -RequiredParameter @('Property2', 'Property3') -IfParameterPresent @('Property1')

        Throws an exception if the parameter 'Property1' is specified and either of the required parameters are not.

    .OUTPUTS
        None.

<#
    .SYNOPSIS
        Throws an error if there is a bound parameter that exists in both the
        mutually exclusive lists.

    .DESCRIPTION
        This command asserts passed parameters. It takes a hashtable, normally
        `$PSBoundParameters`. There are two parameter sets for this command.

        >There is no built in logic to validate against parameters sets for DSC
        >so this can be used instead to validate the parameters that were set in
        >the configuration.

        **MutuallyExclusiveParameters**

        This parameter set takes two mutually exclusive lists of parameters.
        If any of the parameters in the first list are specified, none of the
        parameters in the second list can be specified.

        **RequiredParameter**

        Assert that required parameters has been specified, and throws an exception
        if not. Optionally it can be specified that parameters are only required
        if a specific parameter has been passed.

    .PARAMETER BoundParameterList
        The parameters that should be evaluated against the mutually exclusive
        lists MutuallyExclusiveList1 and MutuallyExclusiveList2. This parameter is
        normally set to the $PSBoundParameters variable.

    .PARAMETER MutuallyExclusiveList1
        An array of parameter names that are not allowed to be bound at the
        same time as those in MutuallyExclusiveList2.

    .PARAMETER MutuallyExclusiveList2
        An array of parameter names that are not allowed to be bound at the
        same time as those in MutuallyExclusiveList1.

    .PARAMETER RequiredParameter
       One or more parameter names that is required to have been specified.

    .PARAMETER IfParameterPresent
       One or more parameter names that if specified will trigger the evaluation.
       If neither of the parameter names has been specified the evaluation of required
       parameters are not made.

    .EXAMPLE
        $assertBoundParameterParameters = @{
            BoundParameterList = $PSBoundParameters
            MutuallyExclusiveList1 = @(
                'Parameter1'
            )
            MutuallyExclusiveList2 = @(
                'Parameter2'
            )
        }
        Assert-BoundParameter @assertBoundParameterParameters

        This example throws an exception if `$PSBoundParameters` contains both
        the parameters `Parameter1` and `Parameter2`.

    .EXAMPLE
        Assert-BoundParameter -BoundParameterList $PSBoundParameters -RequiredParameter @('PBStartPortRange', 'PBEndPortRange')

        Throws an exception if either of the two parameters are not specified.

    .EXAMPLE
        Assert-BoundParameter -BoundParameterList $PSBoundParameters -RequiredParameter @('Property2', 'Property3') -IfParameterPresent @('Property1')

        Throws an exception if the parameter 'Property1' is specified and either
        of the required parameters are not.

    .SYNOPSIS
        This method is used to compare current and desired values for any DSC resource.

    .DESCRIPTION
        This function compare the parameter status of DSC resource parameters against
        the current values present on the system, and return a hashtable with the metadata
        from the comparison.

        >[!NOTE]
        >The content of the function `Test-DscParameterState` has been extracted and now
        >`Test-DscParameterState` is just calling `Compare-DscParameterState`.
        >This function can be used in a DSC resource from the _Get_ function/method.

    .PARAMETER CurrentValues
        A hashtable with the current values on the system, obtained by e.g.
        Get-TargetResource.

    .PARAMETER DesiredValues
        The hashtable of desired values. For example $PSBoundParameters with the
        desired values.

    .PARAMETER Properties
        This is a list of properties in the desired values list should be checked.
        If this is empty then all values in DesiredValues are checked.

    .PARAMETER ExcludeProperties
        This is a list of which properties in the desired values list should be checked.
        If this is empty then all values in DesiredValues are checked.

    .PARAMETER TurnOffTypeChecking
        Indicates that the type of the parameter should not be checked.

    .PARAMETER ReverseCheck
        Indicates that a reverse check should be done. The current and desired state
        are swapped for another test.

    .PARAMETER SortArrayValues
        If the sorting of array values does not matter, values are sorted internally
        before doing the comparison.

    .PARAMETER IncludeInDesiredState
        Indicates that result adds the properties in the desired state.
        By default, this command returns only the properties not in desired state.

    .PARAMETER IncludeValue
        Indicates that result contains the ActualValue and ExpectedValue properties.

    .OUTPUTS
        System.Object[]

    .NOTES
        Returns an array containing a PSCustomObject with metadata for each property
        that was evaluated.

        Metadata Name | Type | Description
        --- | --- | ---
        Property | `[System.String]` | The name of the property that was evaluated
        InDesiredState | `[System.Boolean]` | Returns `$true` if the expected and actual value was equal.
        ExpectedType | `[System.String]` | Return the type of desired object.
        ActualType | `[System.String]` | Return the type of current object.
        ExpectedValue | `[System.PsObject]` | Return the value of expected object.
        ActualValue | `[System.PsObject]` | Return the value of current object.

    .EXAMPLE
        $currentValues = @{
            String = 'This is a string'
            Int = 1
            Bool = $true
        }
        $desiredValues = @{
            String = 'This is a string'
            Int = 99
        }
        Compare-DscParameterState -CurrentValues $currentValues -DesiredValues $desiredValues

        The function Compare-DscParameterState compare the value of each hashtable based
        on the keys present in $desiredValues hashtable. The result indicates that Int
        property is not in the desired state.
        No information about Bool property, because it is not in $desiredValues hashtable.

    .EXAMPLE
        $currentValues = @{
            String = 'This is a string'
            Int = 1
            Bool = $true
        }
        $desiredValues = @{
            String = 'This is a string'
            Int = 99
            Bool = $false
        }
        $excludeProperties = @('Bool')
        Compare-DscParameterState `
            -CurrentValues $currentValues `
            -DesiredValues $desiredValues `
            -ExcludeProperties $ExcludeProperties

        The function Compare-DscParameterState compare the value of each hashtable based
        on the keys present in $desiredValues hashtable and without those in $excludeProperties.
        The result indicates that Int property is not in the desired state.
        No information about Bool property, because it is in $excludeProperties.

    .EXAMPLE
        $serviceParameters = @{
            Name = $Name
        }
        $returnValue = Compare-DscParameterState `
            -CurrentValues (Get-Service @serviceParameters) `
            -DesiredValues $PSBoundParameters `
            -Properties @(
                'Name'
                'Status'
                'StartType'
            )

        This compares the values in the current state against the desires state.
        The command Get-Service is called using just the required parameters
        to get the values in the current state. The parameter 'Properties'
        is used to specify the properties 'Name','Status' and
        'StartType' for the comparison.

    .SYNOPSIS
        Compare current and desired property values for any DSC resource and return
        a hashtable with the metadata from the comparison.

    .DESCRIPTION
        This function is used to compare current and desired property values for any
        DSC resource, and return a hashtable with the metadata from the comparison.

        This introduces another design pattern that is used to evaluate current and
        desired state in a DSC resource. This command is meant to be used in a DSC
        resource from both _Test_ and _Set_. The evaluation is made in _Set_
        to make sure to only change the properties that are not in the desired state.
        Properties that are in the desired state should not be changed again. This
        design pattern also handles when the command `Invoke-DscResource` is called
        with the method `Set`, which with this design pattern will evaluate the
        properties correctly.

        >[!NOTE]
        >This design pattern is not widely used in the DSC resource modules in the
        >DSC Community, the only known use is in SqlServerDsc. This design pattern
        >can be viewed as deprecated, and should be replaced with the design pattern
        >that uses the command [`Compare-DscParameterState`](Compare-DscParameterState).

        See the other design patterns that uses the command [`Compare-DscParameterState`](Compare-DscParameterState)
        or [`Test-DscParameterState`](Test-DscParameterState).

    .PARAMETER CurrentValues
        The current values that should be compared to to desired values. Normally
        the values returned from Get-TargetResource.

    .PARAMETER DesiredValues
        The values set in the configuration and is provided in the call to the
        functions *-TargetResource, and that will be compared against current
        values. Normally set to $PSBoundParameters.

    .PARAMETER Properties
        An array of property names, from the keys provided in DesiredValues, that
        will be compared. If this parameter is left out, all the keys in the
        DesiredValues will be compared.

    .PARAMETER IgnoreProperties
        An array of property names, from the keys provided in DesiredValues, that
        will be ignored in the comparison. If this parameter is left out, all the
        keys in the DesiredValues will be compared.

    .PARAMETER CimInstanceKeyProperties
        A hashtable containing a key for each property that contain a collection
        of CimInstances and the value is an array of strings of the CimInstance
        key properties.
        @{
            Permission = @('State')
        }

    .OUTPUTS
        System.Collections.Hashtable[]

    .NOTES
        Returns an array containing a hashtable with metadata for each property
        that was evaluated.

        Metadata Name | Type | Description
        --- | --- | ---
        ParameterName | `[System.String]` | The name of the property that was evaluated
        Expected | The type of the property | The desired value for the property
        Actual | The type of the property | The actual current value for the property
        InDesiredState | `[System.Boolean]` | Returns `$true` if the expected and actual value was equal.

    .EXAMPLE
        $compareTargetResourceStateParameters = @{
            CurrentValues = (Get-TargetResource $PSBoundParameters)
            DesiredValues = $PSBoundParameters
        }
        $propertyState = Compare-ResourcePropertyState @compareTargetResourceStateParameters
        $propertiesNotInDesiredState = $propertyState.Where({ -not $_.InDesiredState })

        This example calls Compare-ResourcePropertyState with the current state
        and the desired state and returns a hashtable array of all the properties
        that was evaluated based on the properties pass in the parameter DesiredValues.
        Finally it sets a parameter `$propertiesNotInDesiredState` that contain
        an array with all properties not in desired state.

    .EXAMPLE
        $compareTargetResourceStateParameters = @{
            CurrentValues = (Get-TargetResource $PSBoundParameters)
            DesiredValues = $PSBoundParameters
            Properties = @(
                'Property1'
            )
        }
        $propertyState = Compare-ResourcePropertyState @compareTargetResourceStateParameters
        $false -in $propertyState.InDesiredState

        This example calls Compare-ResourcePropertyState with the current state
        and the desired state and returns a hashtable array with just the property
        `Property1` as that was the only property that was to be evaluated.
        Finally it checks if `$false` is present in the array property `InDesiredState`.

    .EXAMPLE
        $compareTargetResourceStateParameters = @{
            CurrentValues = (Get-TargetResource $PSBoundParameters)
            DesiredValues = $PSBoundParameters
            IgnoreProperties = @(
                'Property1'
            )
        }
        $propertyState = Compare-ResourcePropertyState @compareTargetResourceStateParameters

        This example calls Compare-ResourcePropertyState with the current state
        and the desired state and returns a hashtable array of all the properties
        except the property `Property1`.

    .EXAMPLE
        $compareTargetResourceStateParameters = @{
            CurrentValues = (Get-TargetResource $PSBoundParameters)
            DesiredValues = $PSBoundParameters
            CimInstanceKeyProperties = @{
                ResourceProperty1 = @(
                    'CimProperty1'
                )
            }
        }
        $propertyState = Compare-ResourcePropertyState @compareTargetResourceStateParameters

        This example calls Compare-ResourcePropertyState with the current state
        and the desired state and have a property `ResourceProperty1` who's value
        is an array of embedded CIM instances. The key property for the CIM instances
        are `CimProperty1`. The CIM instance key property `CimProperty1` is used
        to get the unique CIM instance object to compare against from both the current
        state and the desired state.

<#
    .SYNOPSIS
        Gets language-specific data into scripts and functions based on the UI culture
        that is specified or that is selected for the operating system.

    .DESCRIPTION
        The Get-LocalizedData command dynamically retrieves strings from a subdirectory
        whose name matches the UI language set for the current user of the operating system.
        It is designed to enable scripts to display user messages in the UI language selected
        by the current user.

        Optionally the `Get-LocalizedData` saves the hash table in the variable
        that is specified by the value of the `BindingVariable` parameter.

        Get-LocalizedData imports data from .psd1 files in language-specific subdirectories
        of the script directory and saves them in a local variable that is specified in the
        command. The command selects the subdirectory and file based on the value of the
        $PSUICulture automatic variable. When you use the local variable in the script to
        display a user message, the message appears in the user's UI language.

        You can use the parameters of G-LocalizedData to specify an alternate UI culture,
        path, and file name, to add supported commands, and to suppress the error message that
        appears if the .psd1 files are not found.

        The G-LocalizedData command supports the script internationalization
        initiative that was introduced in Windows PowerShell 2.0. This initiative
        aims to better serve users worldwide by making it easy for scripts to display
        user messages in the UI language of the current user. For more information
        about this and about the format of the .psd1 files, see about_Script_Internationalization.

    .PARAMETER BindingVariable
        Specifies the variable into which the text strings are imported. Enter a variable
        name without a dollar sign ($).

        In Windows PowerShell 2.0, this parameter is required. In Windows PowerShell 3.0,
        this parameter is optional. If you omit this parameter, Import-LocalizedData
        returns a hash table of the text strings. The hash table is passed down the pipeline
        or displayed at the command line.

        When using Import-LocalizedData to replace default text strings specified in the
        DATA section of a script, assign the DATA section to a variable and enter the name
        of the DATA section variable in the value of the BindingVariable parameter. Then,
        when Import-LocalizedData saves the imported content in the BindingVariable, the
        imported data will replace the default text strings. If you are not specifying
        default text strings, you can select any variable name.

        If the BindingVariable parameter is not specified, Import-LocalizedData returns
        a hashtable of the text strings. The hash table is passed down the pipeline or
        displayed at the command line.

    .PARAMETER UICulture
        Specifies an alternate UI culture. The default is the value of the $PsUICulture
        automatic variable. Enter a UI culture in <language>-<region> format, such as
        en-US, de-DE, or ar-SA.

        The value of the UICulture parameter determines the language-specific subdirectory
        (within the base directory) from which Import-LocalizedData gets the .psd1 file
        for the script.

        The command searches for a subdirectory with the same name as the value of the
        UICulture parameter or the $PsUICulture automatic variable, such as de-DE or
        ar-SA. If it cannot find the directory, or the directory does not contain a .psd1
        file for the script, it searches for a subdirectory with the name of the language
        code, such as de or ar. If it cannot find the subdirectory or .psd1 file, the
        command fails and the data is displayed in the default language specified in the
        script.

    .PARAMETER BaseDirectory
        Specifies the base directory where the .psd1 files are located. The default is
        the directory where the script is located. Import-LocalizedData searches for
        the .psd1 file for the script in a language-specific subdirectory of the base
        directory.

    .PARAMETER FileName
        Specifies the name of the data file (.psd1) to be imported. Enter a file name.
        You can specify a file name that does not include its .psd1 file name extension,
        or you can specify the file name including the .psd1 file name extension.

        The FileName parameter is required when Import-LocalizedData is not used in a
        script. Otherwise, the parameter is optional and the default value is the base
        name of the script. You can use this parameter to direct Import-LocalizedData
        to search for a different .psd1 file.

        For example, if the FileName is omitted and the script name is FindFiles.ps1,
        Import-LocalizedData searches for the FindFiles.psd1 data file.

    .PARAMETER SupportedCommand
        Specifies cmdlets and functions that generate only data.

        Use this parameter to include cmdlets and functions that you have written or
        tested. For more information, see about_Script_Internationalization.

    .PARAMETER DefaultUICulture
        Specifies which UICulture to default to if current UI culture or its parents
        culture don't have matching data file.

        For example, if you have a data file in 'en-US' but not in 'en' or 'en-GB' and
        your current culture is 'en-GB', you can default back to 'en-US'.

    .NOTES
        Before using Import-LocalizedData, localize your user messages. Format the messages
        for each locale (UI culture) in a hash table of key/value pairs, and save the
        hash table in a file with the same name as the script and a .psd1 file name extension.
        Create a directory under the script directory for each supported UI culture, and
        then save the .psd1 file for each UI culture in the directory with the UI
        culture name.

        For example, localize your user messages for the de-DE locale and format them in
        a hash table. Save the hash table in a <ScriptName>.psd1 file. Then create a de-DE
        subdirectory under the script directory, and save the de-DE <ScriptName>.psd1
        file in the de-DE subdirectory. Repeat this method for each locale that you support.

        Import-LocalizedData performs a structured search for the localized user
        messages for a script.

        Import-LocalizedData begins the search in the directory where the script file
        is located (or the value of the BaseDirectory parameter). It then searches within
        the base directory for a subdirectory with the same name as the value of the
        $PsUICulture variable (or the value of the UICulture parameter), such as de-DE or
        ar-SA. Then, it searches in that subdirectory for a .psd1 file with the same name
        as the script (or the value of the FileName parameter).

        If Import-LocalizedData cannot find a subdirectory with the name of the UI culture,
        or the subdirectory does not contain a .psd1 file for the script, it searches for
        a .psd1 file for the script in a subdirectory with the name of the language code,
        such as de or ar. If it cannot find the subdirectory or .psd1 file, the command
        fails, the data is displayed in the default language in the script, and an error
        message is displayed explaining that the data could not be imported. To suppress
        the message and fail gracefully, use the ErrorAction common parameter with a value
        of SilentlyContinue.

        If Import-LocalizedData finds the subdirectory and the .psd1 file, it imports the
        hash table of user messages into the value of the BindingVariable parameter in the
        command. Then, when you display a message from the hash table in the variable, the
        localized message is displayed.

        For more information, see about_Script_Internationalization.

        This command should preferably be used at the top of each resource PowerShell
        module script file (.psm1).

        It will automatically look for a file in the folder for the current UI
        culture, or default to the UI culture folder 'en-US'.

        The localized strings file can be named either `<ScriptFileName>.psd1`,
        e.g. `DSC_MyResource.psd1`, or suffixed with `strings`, e.g.
        `DSC_MyResource.strings.psd1`.

        Read more about localization in the section [Localization](https://dsccommunity.org/styleguidelines/localization/)
        in the DSC Community style guideline.

    .OUTPUTS
        System.Collections.Hashtable

    .EXAMPLE
        $script:localizedData = Get-LocalizedData

        Imports the localized strings for the current OS UI culture. If the localized
        folder does not exist then the localized strings for the default UI culture
        'en-US' is returned.

    .EXAMPLE
        $script:localizedData = Get-LocalizedData -DefaultUICulture 'de-DE'

        Imports the localized strings for the current OS UI culture. If the localized
        folder does not exist then the localized strings for the default UI culture
        'de-DE' is returned.

    .EXAMPLE
        $script:localizedData = Get-LocalizedData -UICulture 'de-DE'

        Imports the localized strings for UI culture 'de-DE'. If the localized folder
        does not exist then the localized strings for the default UI culture 'en-US'
        is returned.

        $script:localizedData = Get-LocalizedData -UICulture 'de-DE' -DefaultUICulture 'en-GB'

        Imports the localized strings for UI culture 'de-DE'. If the localized folder
        does not exist then the localized strings for the default UI culture
        'en-GB' is returned.

<#
    .SYNOPSIS
        Gets language-specific data when the culture is invariant.
        This directly gets the data from the DefaultUICulture, but without calling
        "Import-LocalizedData" which throws when the pwsh session is configured to be
        of invariant culture (as in the Guest Config agent).

    .DESCRIPTION
        The Get-LocalizedDataForInvariantCulture grabs the data from a localized string data psd1 file,
        without calling Import-LocalizedData which errors when called in a powershell session with the
        Globalization-Invariant mode enabled
        (https://docs.microsoft.com/en-us/dotnet/core/compatibility/globalization/6.0/culture-creation-invariant-mode).

        Instead, this function reads and executes the content of a psd1 file in a
        constrained language mode that only allows basic ConvertFrom-stringData.

    .PARAMETER BaseDirectory
        Specifies the base directory where the .psd1 files are located. The default is
        the directory where the script is located. Import-LocalizedData searches for
        the .psd1 file for the script in a language-specific subdirectory of the base
        directory.

    .PARAMETER FileName
        Specifies the base name of the data file (.psd1) to be imported. Enter a file name.
        You can specify a file name that does not include its .psd1 file name extension,
        or you can specify the file name including the .psd1 file name extension.

        The FileName parameter is required when Get-LocalizedDataForInvariantCulture is not used in a
        script. Otherwise, the parameter is optional and the default value is the base
        name of the calling script. You can use this parameter to directly search for a
        specific .psd1 file.

        For example, if the FileName is omitted and the script name is FindFiles.ps1,
        Get-LocalizedDataForInvariantCulture searches for the FindFiles.psd1 or
        FindFiles.strings.psd1 data file.

    .PARAMETER SupportedCommand
        Specifies cmdlets and functions that generate only data.

        Use this parameter to include cmdlets and functions that you have written or
        tested. For more information, see about_Script_Internationalization.

    .PARAMETER DefaultUICulture
        Specifies which UICulture to default to if current UI culture or its parents
        culture don't have matching data file.

        For example, if you have a data file in 'en-US' but not in 'en' or 'en-GB' and
        your current culture is 'en-GB', you can default back to 'en-US'.

    .NOTES
        The Get-LocalizedDataForInvariantCulture should only be used when we want to avoid
        using Import-LocalizedData, such as when doing so will fail because the powershell session
        is in Globalization-Invariant mode:
        https://docs.microsoft.com/en-us/dotnet/core/compatibility/globalization/6.0/culture-creation-invariant-mode

        Before using Get-LocalizedDataForInvariantCulture, localize your user messages to the desired
        default locale (UI culture, usually en-US) in a hash table of key/value pairs, and save the
        hash table in a file with the same name as the script or module with a .psd1 file name extension.
        Create a directory under the module base or script's parent directory for each supported UI culture,
        and then save the .psd1 file for each UI culture in the directory with the UI culture name.

        For example, localize your user messages for the de-DE locale and format them in
        a hash table. Save the hash table in a <ScriptName>.psd1 file. Then create a de-DE
        subdirectory under the script directory, and save the de-DE <ScriptName>.psd1
        file in the de-DE subdirectory. Repeat this method for each locale that you support.

        Import-LocalizedData performs a structured search for the localized user
        messages for a script.

        Get-LocalizedDataForInvariantCulture only search in the BaseDirectory specified.
        It then searches within the base directory for a subdirectory with the same name
        as the value of the $DefaultUICulture variable (specified or default to en-US),
        such as de-DE or ar-SA.
        Then, it searches in that subdirectory for a .psd1 file with the same name
        as provided FileName such as FileName.psd1 or FileName.strings.psd1.

    .EXAMPLE
        Get-LocalizedDataForInvariantCulture -BaseDirectory .\source\ -FileName DscResource.Common -DefaultUICulture en-US

        This is an example, usually it is only used by Get-LocalizedData in DSC resources to import the
        localized strings when the Culture is Invariant (id 127).

    .SYNOPSIS
        Creates a new ErrorRecord.

    .DESCRIPTION
        The New-ErrorRecord function creates a new ErrorRecord with the specified parameters.

    .PARAMETER ErrorRecord
        Specifies an existing ErrorRecord.

    .PARAMETER Exception
        Specifies the exception that caused the error.

        If an error record is passed to parameter ErrorRecord and if the wrapped exception
        in the error record contains a `[System.Management.Automation.ParentContainsErrorRecordException]`,
        the new ErrorRecord should have this exception as its Exception instead.

    .PARAMETER ErrorCategory
        Specifies the category of the error.

    .PARAMETER TargetObject
        Specifies the object that was being manipulated when the error occurred.

    .PARAMETER ErrorId
        Specifies a string that uniquely identifies the error.

    .EXAMPLE
        $ex = New-Exception -Message 'An error occurred.'
        $errorRecord = New-ErrorRecord -Exception $ex -ErrorCategory 'InvalidOperation'

        This example creates a new ErrorRecord with the specified parameters. Passing
        'InvalidOperation' which is one available value of the enum `[System.Management.Automation.ErrorCategory]`.

    .EXAMPLE
        $ex = New-Exception -Message 'An error occurred.'
        $errorRecord = New-ErrorRecord -Exception $ex -ErrorCategory 'InvalidOperation' -TargetObject $myObject

        This example creates a new ErrorRecord with the specified parameters. TargetObject
        is set to the object that was being manipulated when the error occurred.

    .EXAMPLE
        $ex = New-Exception -Message 'An error occurred.'
        $errorRecord = New-ErrorRecord -Exception $ex -ErrorCategory 'InvalidOperation' -ErrorId 'MyErrorId'

        This example creates a new ErrorRecord with the specified parameters. Passing
        ErrorId that will be set as the FullyQualifiedErrorId in the error record.

    .EXAMPLE
        $existingErrorRecord = [System.Management.Automation.ErrorRecord]::new(
            [System.Management.Automation.ParentContainsErrorRecordException]::new('Existing error'),
            'ExistingErrorId',
            [System.Management.Automation.ErrorCategory]::InvalidOperation,

        )
        $newException = [System.Exception]::new('New error')
        $newErrorRecord = New-ErrorRecord -ErrorRecord $existingErrorRecord -Exception $newException
        $newErrorRecord.Exception.Message

        This example first creates an emulated ErrorRecord that contain a `ParentContainsErrorRecordException`
        which will be replaced by the new exception passed to New-ErrorRecord. The
        result of `$newErrorRecord.Exception.Message` will be 'New error'.

    .INPUTS
        System.Management.Automation.ErrorRecord, System.Exception, System.Management.Automation.ErrorCategory, System.Object, System.String

    .OUTPUTS
        System.Management.Automation.ErrorRecord

    .NOTES
        The function supports two parameter sets: 'ErrorRecord' and 'Exception'.
        If the 'ErrorRecord' parameter set is used, the function creates a new ErrorRecord based on an existing one and an exception.
        If the 'Exception' parameter set is used, the function creates a new ErrorRecord based on an exception, an error category, a target object, and an error ID.

<#
    .SYNOPSIS
        This command is used to test current and desired values for any DSC resource.

    .DESCRIPTION
        This function tests the parameter status of DSC resource parameters against
        the current values present on the system.

        This command was designed to be used in a DSC resource from only _Test_.
        The design pattern that uses the command `Test-DscParameterState` assumes that
        LCM is used which always calls _Test_ before _Set_, or that there never
        is a need to evaluate the state in _Set_.

    .PARAMETER CurrentValues
        A hashtable with the current values on the system, obtained by e.g.
        Get-TargetResource.

    .PARAMETER DesiredValues
        The hashtable of desired values. For example $PSBoundParameters with the
        desired values.

    .PARAMETER Properties
        This is a list of properties in the desired values list should be checked.
        If this is empty then all values in DesiredValues are checked.

    .PARAMETER ExcludeProperties
        This is a list of which properties in the desired values list should be checked.
        If this is empty then all values in DesiredValues are checked.

    .PARAMETER TurnOffTypeChecking
        Indicates that the type of the parameter should not be checked.

    .PARAMETER ReverseCheck
        Indicates that a reverse check should be done. The current and desired state
        are swapped for another test.

    .PARAMETER SortArrayValues
        If the sorting of array values does not matter, values are sorted internally
        before doing the comparison.

    .OUTPUTS
        [System.Boolean]

    .EXAMPLE
        $currentState = Get-TargetResource @PSBoundParameters
        $returnValue = Test-DscParameterState -CurrentValues $currentState -DesiredValues $PSBoundParameters

        The function Get-TargetResource is called first using all bound parameters
        to get the values in the current state. The result is then compared to the
        desired state by calling `Test-DscParameterState`. The result is either
        `$true` or `$false`, `$false` if one or more properties are not in desired
        state.

    .EXAMPLE
        $getTargetResourceParameters = @{
            ServerName = $ServerName
            InstanceName = $InstanceName
            Name = $Name
        }
        $returnValue = Test-DscParameterState `
            -CurrentValues (Get-TargetResource @getTargetResourceParameters) `
            -DesiredValues $PSBoundParameters `
            -ExcludeProperties @(
                'FailsafeOperator'
                'NotificationMethod'
            )

        This compares the values in the current state against the desires state.
        The function Get-TargetResource is called using just the required parameters
        to get the values in the current state. The parameter 'ExcludeProperties'
        is used to exclude the properties 'FailsafeOperator' and 'NotificationMethod'
        from the comparison. The result is either `$true` or `$false`, `$false` if
        one or more properties are not in desired state.

    .EXAMPLE
        $getTargetResourceParameters = @{
            ServerName = $ServerName
            InstanceName = $InstanceName
            Name = $Name
        }
        $returnValue = Test-DscParameterState `
            -CurrentValues (Get-TargetResource @getTargetResourceParameters) `
            -DesiredValues $PSBoundParameters `
            -Properties ServerName, Name

        This compares the values in the current state against the desires state.
        The function Get-TargetResource is called using just the required parameters
        to get the values in the current state. The 'Properties' parameter is used
        to to only compare the properties 'ServerName' and 'Name'.

        it is assigned a non-null value.

    .PARAMETER InputObject
        Specifies the object that should be tested for existens of the specified
        property.

    .PARAMETER Name
        Specifies the name of the property.

    .PARAMETER HasValue
        Specifies if the property should be evaluated to have a non-value. If
        the property exist but is assigned `$null` the command returns `$false`.

    .EXAMPLE
        $this | Test-DscProperty -Name 'MyDscProperty'

        Returns `$true` or `$false` whether the property exist or not.

    .EXAMPLE
        Test-DscProperty -InputObject $this -Name 'MyDscProperty' -HasValue

        Returns `$true` if the property exist and is assigned a non-null value,
        if not `$false` is returned.

    .EXAMPLE
        Test-DscProperty -InputObject $this -Name 'MyDscProperty' -Attribute 'Optional'

        Returns `$true` if the property exist and is an optional property.

    .EXAMPLE
        Test-DscProperty -InputObject $this -Name 'MyDscProperty' -Attribute 'Optional' -HasValue

        Returns `$true` if the property exist, is an optional property, and is
        assigned a non-null value.

    .OUTPUTS
        [System.Boolean]

    .NOTES
        This command only works with nullable data types, if using a non-nullable
        type make sure to make it nullable, e.g. [Nullable[System.Int32]].
