Visual Studio 2015 solutions backwards compatibility with Visual Studio 2013

Question

It seems that I can open a VS 2013 solution file in VS 2015. I\'ve a few questions regarding backwards compatibility:

• Can a VS 2013 solution be maintained in V

Answer 1

I feel this is a legitimate question; I've not seen any official information from Microsoft regarding round-tripping solutions between the two IDEs, other than to "assume it works".

From my personal experience in the last 24 hours, "upgrading" the solution file with VS2015 causes no harm in and of itself; it changes the version number in the solution file and it re-sorts things but it doesn't add/remove anything else.

It will try and change some csproj files if they are tagged with an older tools version, but things still compile.

Unfortunately, we have made little progress with VS2015 because we rely on Microsoft fakes for stubs, and there appears to be at least one bug with that tool that is stopping us from continuing (see Visual Studio 2015, Microsoft Fakes and System.Security.Claims.Claim).
