    Hi ,

    I have Installed Windows Management Framework (WMF) 5.0 RTM edition that was released 2015-12-17 to encrypti the Credentials in DSC MOF Files. but while try to create the mof, i was getting the error shown below .

    Dsc script
    $ConfigData= @{
    AllNodes = @(
    # The name of the node we are describing
    NodeName = “localhost”

    # The path to the .cer file containing the
    # public key of the Encryption Certificate
    # used to encrypt credentials for this node"
    CertificateFile ="C:\Publickeys\Pullserver.cer"

    # The thumbprint of the Encryption Certificate
    # used to decrypt the credentials on target node
    Thumbprint ="7af113abe96aede262fe965983248dd533306d7f"

    configuration test

    [PsCredential] $credential

    Import-DscResource -ModuleName PSDesiredStateConfiguration -ModuleVersion 1.1
    node $AllNodes.NodeName
    File exampleFile
    SourcePath = "\\sptest\C\devcon\devcontest.txt”
    DestinationPath = "\\sptest\C\credsencrpt"
    Credential = $credential

    CertificateId = $node.Thumbprint


    test -configurationdata $ConfigData -outputpath c:\credsencrpt

    Error :

    You want to use WMF 5.0 RTM re-released in Feb instead of Dec one @ https://www.microsoft.com/en-us/download/details.aspx?id=50395.
    I tried it and compilation is succeeding.
