Make sure you call:

C:\Program Files (x86)\MSBuild\14.0\Bin\MsBuild.exe

That's the version of MsBuild that ships with Visual Studio 2015 and calls the C# compiler that understands this. You can get this version of MsBuild on your system by installing any edition of Visual Studio 2015 or by installing the stand-alone Microsoft Build Tools 2015.

Adding a reference to the following NuGet package will also force use of the new compiler:

Install-Package Microsoft.Net.Compilers

Please note Install-Package will pick the latest available version which may not be the one you are looking for. Before you install, please check the release notes and dependencies to resolve the underlying issue with the version being dealt with, which in this case, was more specific to VS 2015.

So for Visual Studio 2015:

Install-Package Microsoft.Net.Compilers -Version 1.0.0
