How to solve a crossdomain policy security exception in C#

I have been trying to create a C# IRC client, I've got everything working, and when connecting to some networks it throws a socket policy exception as follows:

System.Security.Securi开发者_如何学CtyException: Unable to connect, as no valid crossdomain policy was found at System.Net.Sockets.Socket.Connect_internal (IntPtr sock, System.Net.SocketAddress sa, System.Int32& error, Boolean requireSocketPolicyFile) [0x00000] in :0 at System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP, Boolean requireSocketPolicy) [0x00000] in :0 at System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP) [0x00000] in :0 at System.Net.Sockets.TcpClient.Connect (System.Net.IPEndPoint remote_end_point) [0x00000] in :0 at system.Net.Sockets.TcpClient.Connect (System.Net.IPAddress[] ipAddresses, Int32 port) [0x00000] in :0

Here's the code I am using to connect:

//connect the client
client = new TcpClient(serverAddress, serverPort);

The moment it tries to connect to most IRC servers it throws that exception, but for some it doesn't, as you probably realize I need the client to connect to any irc server that allows it.

I have tried searching for solutions on Google but all it came up with was Silverlight exceptions, I am not using Silverlight. I've been trying to resolve this for a week with no luck, I've been programming for 8 years, and I am quite adept at solving problems, but this is beyond me so any help is appreciated.

Have you tried running the assembly as an administrator? If that works then it's a security issue and you need to specify the permission your program requires. So, if "Run as Admin" works, check: http://msdn.microsoft.com/en-us/library/system.net.socketpermissionattribute%28v=VS.110%29.aspx
