For the most part, I find that Visual Studio 2015 is awesome. However, it did ship with kinks that need to be worked out. Not least, it has crashed on me from time to time, while working on a large solution.

I recently experienced a problem where I couldn't open Visual C++ projects (.vcxproj) after I copied them to another location. When trying to open the projects, VS 2015 would give me nothing more than this "extremely useful" error:

That is some talent, right there. That must have taken a lot of work to get this right.

After trying various things, and having researched this without success for a few hours, I finally got the idea to try opening the projects in Visual Studio 2013, instead.

Behold: VS 2013 actually displayed a useful error, which informed me that my projects had Import dependencies that I forgot to move.

So, yeah. If VS 2015 helpfully tells you that "one or more errors occurred" — try VS 2013.
