C# using RDM socket

------------ I declared it with : server = new Socket( AddressFamily.InterNetwork, SocketType.Rdm, ProtocolType.Tcp ); It gave me an error: System.Net.Sockets.SocketException: The requested protocol has not been configured into the system, or no implementation for it exists at System.Net.Sockets.Socket..ctor(AddressFamily addressFamily, SocketType socketType, ProtocolType protocolType) -------------------- I dont have any idea how to configure this socket. I have searched MSDN library, but still not much information are provided. I need it because I need to build a multicast application with reliable multicast protocol like PGM ( pragmatic general multicasting ). If you all have other suggestions, please kindly let me know. I am really desperated to finish this project. Thank you so much.
