    .DESCRIPTION
        This function determines if a package is a preview build based on the version string

    .PARAMETER Version
        The version string (e.g., "7.6.0-preview.6" or "7.6.0")
    .PARAMETER LTS
        Whether this is an LTS build
    .OUTPUTS

    .EXAMPLE
        Get-MacOSPackageIdentifierInfo -Version "7.6.0-preview.6" -LTS:$false

.SYNOPSIS
Create a reference assembly from System.Management.Automation.dll

.DESCRIPTION
A unix variant of System.Management.Automation.dll is converted to a reference assembly.
GenAPI.exe generated the CS file containing the APIs.
This file is cleaned up and then compiled into a dll.

.PARAMETER Unix64BinPath
Path to the folder containing unix 64 bit assemblies.

.PARAMETER RefAssemblyDestinationPath
Path to the folder where the reference assembly is created.

.PARAMETER RefAssemblyVersion
Version of the reference assembly.

.PARAMETER GenAPIToolPath
Path to GenAPI.exe. Tool from https://www.nuget.org/packages/Microsoft.DotNet.BuildTools.GenAPI/

.PARAMETER SnkFilePath
Path to the snk file for strong name signing.
