function Get-DbaSqlInstanceProperty {
    <#
        .SYNOPSIS
            Gets SQL Server instance properties of one or more instance(s) of SQL Server.
 
        .DESCRIPTION
            The Get-DbaSqlInstanceProperty command gets SQL Server instance properties from the SMO object sqlserver.
 
        .PARAMETER SqlInstance
            SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
        .PARAMETER SqlCredential
            Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
        .PARAMETER InstanceProperty
            SQL Server instance property(ies) to include.
 
        .PARAMETER ExcludeInstanceProperty
            SQL Server instance property(ies) to exclude.
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
