title: Importing C# dll to C++ managed code (.NET)
body: <p>I'm using Visual Studio 2010. I've written a dll in C#, managed dll then.
  Now for some reason, I need to write a software in C++ (.NET then also managed).
  I need to import the C# dll into my C++ .NET code. 
  I can't figure out to do this, I've made several search but this problem seems to not be covered. For example, in C# I don't have include file, then how my C++ (.NET) projet knows about classes and functions inside the dll?
  Thanks,</p>
