I have an independent solution with multiple projects including class libraries and control libraries. This solution and all its projects are under TFS source control.
I reference the output of one or more of these libraries in all new projects I develop. References are currently binary rather than project references.
The new projects are also always under source control and now I need to add debugging support for the libraries.
If I reference the library projects from them, the project file is modified and no longer works with the original library solution since source control providers for the library and referencee may be different.
Is there an easy way to accommodate this?

right click on your new project's solution-->Add-->Existing Projectand browsing for the required library/libraries? I'm not 100% sure as I don't currently have access to VS but I think that just might solve your issue. - snajahi
