        .SYNOPSIS
            Creates Visual C++ Redistributable applications in a Microsoft Deployment Toolkit share.

        .DESCRIPTION
            Creates an application in a Microsoft Deployment Toolkit share for each Visual C++ Redistributable and includes properties such as target Silent command line, Platform and Uninstall key.

            Use Get-VcList and Get-VcRedist to download the Redistributables and create the array for importing into MDT.

        .PARAMETER VcList
            An array containing details of the Visual C++ Redistributables from Get-VcList.

        .PARAMETER Path
            A folder containing the downloaded Visual C++ Redistributables.

        .PARAMETER MdtPath
            The local or network path to the MDT deployment share.

        .PARAMETER Silent
            Add a completely silent command line install of the VcRedist with no UI. The default install is passive.

        .EXAMPLE
            Get-VcList | Save-VcRedist -Path C:\Temp\VcRedist | Import-VcMdtApp -Path C:\Temp\VcRedist -MdtPath \\server\deployment

            Description:
            Retrieves the default list of supported Visual C++ Redistributables, downloads them to C:\Temp\VcRedist and imports each Redistributable into the MDT deployment share at \\server\deployment.

        .EXAMPLE
            $VcList = Get-VcList -Export All
            Save-VcRedist -VcList $VcList -Path C:\Temp\VcRedist
            Import-VcMdtApp -VcList $VcList -Path C:\Temp\VcRedist -MdtPath \\server\deployment -Bundle

            Description:
            Retrieves the list of supported and unsupported Visual C++ Redistributables in the variable $VcList, downloads them to C:\Temp\VcRedist, imports each Redistributable into the MDT deployment share at \\server\deployment and creates an application bundle.
