When you are writing and debugging SmartClient applications yu often want to be able to seamlessly debug across the web service boundary. That is, you want to be able to set break points in both your server and cient side code.

This often means that you need to have both projects running in the debugger.

I just found out that VS.NET supports this nativly.

Go to the Solution Properties of your solution and check the 'Multiple Startup projects' radio button. You can then set the order in which certain projects are started up. e.g. Start the web services first and then startup your smart client project.

Very cool- you learn something new every day.
