Upgrade/Load-NAVCumulativeUpdateHelper.ps1

<#
    .Synopsis
        Loads a .Net assembly to easily find Microsoft Dynamics NAV downloads in the Microsoft Download Center.
    .DESCRIPTION
        Compiles C# in memory and gives you 2 static functions:
            static System.Collections.Generic.IEnumerable[MicrosoftDownload.NAVDownload] GetDownloadLocales(int productID)
            static System.Collections.Generic.IEnumerable[MicrosoftDownload.NAVDownload] GetDownloadDetail(int productID, string language)
        See examples for how to use them.
        The functions only work when you have a ProductID for Microsoft Dynamics NAV Download Center. The function "Get-NAVCumulativeUpdateFile" shows you how to get to the ProductID for Cumulative Updates.
    .EXAMPLE
        Load-NAVCumulativeUpdateHelper
        $Locales = [MicrosoftDownload.MicrosoftDownloadParser]::GetDownloadLocales(54317)
        $MyDownload = $Locales | out-gridview -PassThru | foreach {
            $_.DownloadUrl
            Start-BitsTransfer -Source $_.DownloadUrl -Destination C:\_Download\Filename.zip
        }
    .EXAMPLE
        Load-NAVCumulativeUpdateHelper
        $MyDownload = [MicrosoftDownload.MicrosoftDownloadParser]::GetDownloadDetail(54317, 'en-US') | Select-Object *
    .OUTPUT
        THe function gives you the ability to run two static functions: "GetDownloadLocales" and "GetDownloadDetail"
