Problem is I have created a public RemoteProcedureCalls

Server: RemoteProcedureCalls.Server.RegisterInstanceForPublicRemoteCall<DownloaderRemote, IDownloaderRemote>(new DownloaderRemote(), “DownloaderRemoteInst”);
TCPConnection.StartListening(new IPEndPoint(IPAddress.Parse(serverIP), _serverPort));

Client:
var connectionInfo = new ConnectionInfo(“127.0.0.1”, 654);
var con = TCPConnection.GetConnection(connectionInfo);
string instanceId;
_downloader = RemoteProcedureCalls.Client.CreateProxyToPublicNamedInstance<IDownloaderRemote>(con, “DownloaderRemoteInst”, out instanceId);

Everything seems to work until i want to call a function on the interface
i get JIT Compiler encountered an internal limitation.

I am using VS2012 .Net40

best regards
