Subject Re: Drop support for VS2013 in REEF.NET
Date Thu, 06 Oct 2016 00:11:35 GMT
+1 on the general idea of moving to more modern versions of Visual
Studio and .NET as a requirement.  However:

there were some hesitations about moving to .NET 4.6 as a runtime
requirement when we discussed this as a step towards a .NET Core
version of REEF.NET. Boris was one of the people who had concerns. Do
they still exist?

I believe moving to Visual Studio 2015 does not also require us to
move to .NET 4.6 as the required runtime environment. Hence, that
change might be a bit easier and could be done first.
