Debugging multiple projects

Question

This forum lacks a Visual Studio.NET forum, so I'll post here. I have a solution with a few projects (WinClient, Class library, Web service project). When I start debugging the client, it only loads symbols for Client project and therefore debugger doesn't stop to breakpoint in WebService project. I have to manually attach the debugger to another running process (aspnet_wp.exe). Is there a way to automate this? I found that I can set multiple startup projects for a solution, but it didn't work as desired.
