What exactly does <system.codedom>/<compilers> do in web.config in MVC 5?
问题 I am about to migrate a bunch of projects from .NET 4.0 + MVC 3 to .NET 4.5.2 + MVC5. To make this easier, I've created a new blank MVC project to compare DLL references and some other stuff such as web.config. In the latter, the following entries are generated by Visual Studio: <system.codedom> <compilers> <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1
