ASP.NET strange compilation error

Question

I don't know what's wrong with my machine, but it's a while that I'm getting the following strange error from ASP.NET (for all my applications).

Compilation Error  Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.   Compiler Error Message: The compiler failed with error code -1073741502.

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

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: The compiler failed with error code -532462766.
