compile dll to work in other languages

Question

Is it possible to compile c# dll in a way that it can be imported in different programming languages or does it work only with visual studio projects?

Answer 1

The [ComVisible] attribute allows C# code to be used in practically any language that can run on Windows. COM support in a language runtime was pretty mandatory to give a language a chance to be adopted on Windows. You'd of course use whatever tooling is available for the language, it doesn't require VS.
