How do I add an MSBuild .proj file to my solution?

Question

Does anyone know how to add a an MSBuild .proj file to my solution?

I was just given existing code from a vendor with a solution that references an MSBuild .proj file as one of its projects. When I open the solution, the project shows as (unavailable). It appears that I need to install some sort of project template to get this project to open correctly. I installed the Codeplex MSBuild Template, but this doesn't appear to be it.

Any ideas?

I actually got it to work! I re-started Visual Studio and still saw that the projects were unavailable after installing the MSBuild Template mentioned above. I had to manually reload the projects. That fixed the issue.
