Reference for Socket programming in MS Visual Studio

[WDT]

Hi

I'm learning socket programming in C# at the moment in Visual studio 2008 Express.
Because I started off with an empty project I have to add in the references myself, however I can't find the references for the statement:

Using System.Net.Sockets;

The closest I can get to in the option to add a reference is System.Net which doesn't work. Is this a purposeful omittance by MS from the Express edition?

If you reference "System" you should gain access to System.Net.Sockets.
