Debugging using two instances of visual studio

Hello,

I have 2 solutions, each solution has multiple projects and they are source controlled separately.

In Solution A I have a DLL that is referenced, I have the source control for this in Solution B. I would like to "Step into" on a call in Solution A and have the debugger kick in on Solution B.

Is this possible?

I have done something similar to this when writing webservices. The Webservice is in project B and is already running when project A makes a call. Both instances of visual studio can be used for debugging.

Any suggestions are welcome,

Thanks,
