The project csproj files are referencing to older versions of Microsoft.Net.Compilers (should be: 2.1.0) and Microsoft.CodeDom.Providers.DotNetCompilerPlatform (should be 1.0.7). This could be resolved via a nuget package install for the whole solution. Also a global web.config file is needed for the process (with Build Action set to None).
