Just putting this here, because I spent two days trying to resolve this same issue (roslyn csc.exe not copied), but none of these answers solved my problem.

It turns out that Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.6 (and 1.0.7) is broken. Downgrade to 1.0.5.

I was getting the same errors as everyone else here, but I'm using VS 2017, and both local WebDeploy as well as AzureDeploy were broken (no csc.exe found).
