function New-SADPowerFormProject
{
    <#
    .SYNOPSIS
    Generates a new PowerForm project from a custom template using the Plaster PowerShell module.
 
    .DESCRIPTION
    This function generates a new PowerForm project based on a custom template. A PowerForm is a PowerShell script that generates and displays a Microsoft Windows form that can be used for a specific management or system administration task in a computer network environment. Typically, a PowerForm is compiled into an executable file which hides the PowerShell console window during execution and provides a more seamless and familiar experience to the user.
     
    A PowerForm project is the set of files and folders including the PowerShell script, typically stored in a GIT repository, that are used to compile the executable file using the Microsoft .NET CLI utility (dotnet.exe) which is available with any Microsoft .NET SDK. The PowerForm project includes a C# file which the compiler will use as the source for the executable, and a C# project file (csproj file) which provides the set of instructions used to compile the executable.
     
    A PowerForm project consists of the following folder structure:
 
    PowerFormName
    |--Build
       | Build.cs
       | Build.csproj
    | .gitignore
    | Readme.md
    | PowerFormName.ps1
 
    If Visual Studio Code is installed, it will be opened to the new project directory location after the directory structure is created.
 
    .PARAMETER Size
    Specifies the initial size of the PowerForm to generate. The following pre-configred sizes are available to select:
 
    Large: Used to build a general purpose PowerForm using a large sized form
    Medium: Used to build a general purpose PowerForm using a medium sized form
    Small: Used to build a general purpose PowerForm using a small sized form
 
    .PARAMETER DestinationPath
    Specifies the root destination path of the new PowerForm project directory. A directory, using the value of the "Name" parameter, will be created under this path to hold the project files.
 
    .PARAMETER Name
    Specifies the name of PowerShell script as well as the name of the project directory. As a best practice, this name should describe what the script does in VERB-NOUN format. The name will be substituted into various locations within the project such as the Readme.md file and the comments section of the PowerShell script.
 
    .PARAMETER Author
    Specifies the PowerForm author that will be substituted into the comments section of the PowerShell script. By default this parameter will be set to the Git user name or the current user login name if Git is not installed.
 
    .PARAMETER NoLogo
    Specifies if the Plaster logo is shown during function execution.
 
    .EXAMPLE
    PS C:\>New-SADPowerFormProject -Size Small -DestinationPath $HOME\Desktop -Name Show-SmallForm
 
    Description
    -----------
    Deploys a new small size PowerForm project named "Show-SmallForm" on the users desktop in the "Show-SmallForm" directory. If Git is installed, the Git user name will be used as the author name in the project.
    If Git is not installed, the current user login name will be used instead.
 
    .EXAMPLE
    PS C:\>New-SADPowerFormProject -Size Medium -DestinationPath $HOME\Desktop -Name Show-MediumForm
 
    Description
    -----------
    Deploys a new medium sized PowerForm project named "Show-MediumForm" on the users desktop in the "Show-MediumForm" directory. If Git is installed, the Git user name will be used as the author name in the project.
    If Git is not installed, the current user login name will be used instead.

function Build-SADPowerFormExecutable
{
    <#
    .SYNOPSIS
    Compiles a new PowerForm executable file from an existing PowerForm project located in the current working directory.
 
    .DESCRIPTION
    This function performs the following steps for building a PowerForm assembly:
    - Searches the current working directory for PowerShell script files and digitally signs each one found if an appropriate code-signing certificate is available.
    - Searches the current working directory for the Microsoft .NET build files and compiles the specified PowerShell script into a executable for each build target specified.
    - Searches the current working directory for compiled executable files and digitally signs each one found if an appropriate code-signing certificate is available.
 
    .PARAMETER BuildTarget
    Specifies the .NET target framework to use for build the executable(s). Selecting "All" (the default value) will compile the an executable for all available frameworks.
     
    .PARAMETER BuildFolder
    Specifies the path to the Microsoft .NET build files.
 
    .PARAMETER CertificateFriendlyName
    Specifies the friendly name of the code-signing certificate.
 
    .PARAMETER CLI
    Specifies the path to the Microsoft .NET CLI used for compiling the executable(s).
 
    .PARAMETER ProjectFileName
    Specifies the path to the project file used to provide build instructions for the Microsoft .NET CLI.
 
    .PARAMETER ReleaseFolder
    Specifies the path to the target folder for the executable(s).
 
    .PARAMETER TimeStampServer
    Specifies the URL to the time stamp web server used for digitally signing files.
 
    .EXAMPLE
    PS C:\>Build-SADPowerFormExecutable
 
    Description
    -----------
    Invokes the build process using all default parameters and targets all available Microsoft .NET frameworks.
 
    .EXAMPLE
    PS C:\>Build-SADPowerFormExecutable -CertificateFriendlyName "CodeSigningCert"
 
    Description
    -----------
    Invokes the build process using a custom certificate with the friendly name "CodeSigningCert".
 
    .EXAMPLE
    PS C:\>Build-SADPowerFormExecutable -BuildTarget Legacy
 
    Description
    -----------
    Invokes the build process using all default parameters but targets only the legacy .NET 4 framework.
