Running build.cmd throws the error: MS 14.0 does not support Microsoft.Net.Compilers.
I have resolved this issue by using a newer Msbuild.exe:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\MSBuild.exe" %_solution% /p:DeployOnBuild=true /p:PublishProfile=%_publishProfile% /p:VisualStudioVersion=15.0
