Could not load file or assembly 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The module was expected to contain an assembly manifest.

Why do I keep getting this error and how can I fix it?

I think the Nuget package Microsoft.CodeDom.Providers.DotNetCompilerPlatform is of wrong version. Try updating the Nuget package. – Nitin
