C#

Anyone know a solution for the following?
I'm creating a program that has both a server and a client. Now I have both sides included in a single project.
What is the best solution for debugging this? i.e. how do I start the 2 classes at once (multiple processes/threads?).

Or would you recommend an alternate approach (splitting the project but sharing certain classes?), and is it possible to start multiple projects in a solution when debugging?

I think you misunderstood me.
Currently the project runs either the server or the client class, depending on command line parameters.
What I'd like it to do, is when I start debugging in the IDE, it not only runs one of the components, but both, so I can test the interactions between the two.
