    Hi ,

    I have Installed Windows Management Framework (WMF) 5.0 RTM edition that was released 2015-12-17 to encrypt 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

    {
    param(
    [Parameter(Mandatory=$true)]
    [ValidateNotNullorEmpty()]
    [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
    }

    LocalConfigurationManager
    {
    CertificateId = $node.Thumbprint

    }
    }
    }

    test -configurationdata $ConfigData -outputpath c:\credsencrpt

    Error :

    PS C:\Windows\system32> C:\credsencrpt\creden.ps1

    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.

    Seems like somehow you end up using old SMA.dll instead of the one from WMF 5.0 RTM. Can you restart your machine and try again? I will also try to find the root cause.
