Builds are failing on latest stable of XS when trying to build code with C# 6.0 features. What version of MSBuild does XS on Windows use, what is its path, and if there is one, what is the plan for supporting and/or using Microsoft Build Tools 2015?
I was recently looking into this, and it appears that we hard-code a preference for tools version 12 (VS2013):
VS2015 is tools version 14.
Michael pointed out that this can be worked around by adding this to your csproj:
<PropertyGroup Condition="'$(Platform)' != 'Unix'">
Alternatively, you can set a CscToolPath system environment variable to the expanded value of that expression (which I have done, and it's working great now).
As per above discussion, marking this issue as Confirmed.
