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?

You use a debugger, of course.

Alternately, implement a test program that outputs all data that is passed and processed by either side, log that, then review the logs analytically.

There are probably more elegant ways to debug a client-server application but I've always found the brute force method of telling the program to put all its cards for the time being on the table is most thorough.
