FIM CM C# returns System.InvalidCastException

Hello everyone,

i have a problem with a ConsoleApplication which I am actually writing for FIM CM. The problem appears with or without .Net remoting I tested both. 

The problem appears at this little piece of code:

public static ReadOnlyCollection<ProfileTemplate> FindAllProfileTemplates(FindOperationsByCulture findOperationsByCulture)
{

       FindOperations.UseRemoting = true;
       return findOperationsByCulture.FindAllProfileTemplates(CultureInfo.InvariantCulture, CultureInfo.InvariantCulture);
}

And in my main method I am calling the function like this:

ReadOnlyCollection<ProfileTemplate> templates = FindAllProfileTemplates(findOperationsByCulture);

Which leads to the Exception mentioned in the title:

Unhandled Exception: System.InvalidCastException: Return argument has an invalid
 type.
   at System.Runtime.Remoting.Proxies.RealProxy.ValidateReturnArg(Object arg, Ty
pe paramType)
   at System.Runtime.Remoting.Proxies.RealProxy.PropagateOutParameters(IMessage
msg, Object[] outArgs, Object returnValue)
   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgDa
ta, Int32 type)
   at Microsoft.Clm.Provision.FindOperationsByCulture.FindAllProfileTemplates(Cu
ltureInfo uiCulture, CultureInfo culture)

Can anybody explain me what am I doing wrong? I took the PowerShell example from Craig Martin (http://www.integrationtrench.com/2010/11/use-fim-cm-provision-api-from.html) and in PowerShell everything works like a charm. I do the same (but ajdusted it for C#) and i get this exception.

I post the whole Code of the program here, so maybe the Problem is in another place of the code.

Every help is highly appreciated :-)

Thank you very much!

Tom
