Is there any way to get Visual Studio to reload all projects when the .proj files have changed?

if you install this plugin from the visual studio gallery:

The button "Reload all" appears.

Deleting my solution_name.v11.suo file (hidden file stored in same location as solution file) seemed to do the trick.

Unfortunately, VS doesn't come with a way to do this. A probable workaround is to touch the solution file before activation VS. It would then reload the whole solution.

There must, however, be ways to do this programmatically, since I remember CMake solutions asking me whether I wanted to reload the whole solution after individual projects were re-generated. CMake is Open Source, so if you're really desperate, you might want to look into it.
