Which compiler is used when building solution in Visual Studio?

Question

I was reading up on JIT and AOT compiler and found that CLR in .NET uses JIT compilation. But I also read that the build process in Visual Studio includes compilation and linking, among other things.

I assume JIT compilation happens when the request hits IIS. What kind of compilation happens during the build phase in Visual Studio?

Answer 1

JIT is a "Just-In-Time" compiler which is used to compile IL to the machine commands. Compiler compiles your code to the IL language.

Compiler used to compile solution is MSBuild/Roslyn. There are other compilers used to compile e.g. web pages like ASP.NET Compilation Tool.
