Running two projects at once in Visual Studio

Question

I created a solution in Visual C# 2010 Express that contains two projects: one is the client, the other is the server. I would like to debug both at the same time, but I can only seem to run one of the projects during debugging.

Is there a way to run both at once?

Answer 1

You may find it easiest to just use two instances of Visual Studio. You could make a solution with just the server project in it, so that you can set the startup project separately for each solution

Answer 2

Go to Solution properties -> Common properties -> Startup Project and select Multiple startup projects

Answer 3

Max nailed it. I have a post here that shows some screenshots for those interested: http://blogs.msdn.com/b/zainnab/archive/2010/05/10/multiple-startup-projects-vstipenv0015.aspx

Answer 4

Max has the best solution for when you always want to start both projects, but you can also right click a project and choose Debug > Start New Instance.

This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).
