Minimum Visual Studio Version for Visual studio 2015 solution

Question

I have upgraded a project from VS 2013 to VS 2015. Everything works great, I can now open the same Project in both VS 2013 and VS 2015.

Now, with this new Roslyn compiler of VS 2015, I assume that when I introduce some new C# 6 features in the Project, I will be able to open the Project only in VS 2015.(In 2013 I will get some compiler errors)

What would be the MinimumVisualStudioVersion to enter in the .sln file, until now I was able to open the solution in VS 2013, VS 2012 and also VS 2010:

# Visual Studio 2013
VisualStudioVersion = 12.0.40629.0
MinimumVisualStudioVersion = 10.0.40219.1

This means that it was possible to open VS2013 Projects in VS 2010 without Problems.

But, with the new compiler features of 2015, does that mean that the MinimumVisualStudioVersion has to be >= to 14.x.xxxxx.x for VS 2015 Projects?

Answer 1

This means that the minimum version of Visual Studio to open this solution is 10.0.40219.1 which is actually Visual Studio 2010 SP1.
