You may think this question is the exact duplicate of Running two projects at once in Visual Studio. Not really, it is the exact opposite.
I have a VS 2010 solution with two MVC3 projects. I've already configured the solution with a single startup project. However, each time I run it, VS spawns two servers with the two MVC applications (and one does not have direct dependency on the other).
So, how do I get rid of such behavior?
