Sorry please find the correct client code which gives exception /////////////////////////////////////////////////////////// InstanceContext ct = new InstanceContext(new Program()); //generated proxy KineticServiceClient client = new KineticServiceClient(ct); Dictionary response = null; Dictionary> request = new Dictionary>(); List lst= new List(); lst.Add("hello"); lst.Add(23); /* Dictionary dict = new Dictionary(string,string>); dict.Add("1", "10"); dict.Add("2", "10"); dict.Add("3", "10"); lst.Add(dict); */ request.Add("test1",lst); client.Func(out response, request);

Hi, I have created two programs to test WCF using TCPIP binding. One program is acting as a client and other is acting as a server. Server has one function which is something like /////////////////////////////////////////////////////////// public bool Func(out Dictionary > response,Dictionary > request) { return true; } /////////////////////////////////////////////////////////// The client on the other hand has following code for using this function /////////////////////////////////////////////////////////// InstanceContext ct = new InstanceContext(new Program()); //generated proxy KineticServiceClient client = new KineticServiceClient(ct); Dictionary> response = null; Dictionary> request = new Dictionary>(); List lst= new List(); lst.Add("hello"); lst.Add(23); /* Dictionary dict = new Dictionary(); dict.Add("1", "10"); dict.Add("2", "10"); dict.Add("3", "10"); lst.Add(dict); */ request.Add("test1",lst); client.Func(out response, request); //////////////////////////////////////////////////////////////////// Everything works fine until I uncomment above commented code in client program.
