Facts:

1. Killing worker process fixes the problem temporarily
2. I even reinstalled my .NET framework! It didn't work.
3. Restarting IIS doesn't help

What can cause this problem?

Answer 1

I removed Roslyn related packages by NuGet and it does work now.

Roslyn related packages:

• Microsoft.CodeDom.Providers.DotNetCompilerPlatform
• Microsoft.Net.Compilers

P.S: My local IIS doesn't have any problem with Roslyn but as I publish the project on the server (this is why I don't think the server supports Roslyn), it shows the following error message:

Compilation Error
