Importing C# dll to C++ managed code (.NET)

Question

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,

You just need to add only reference of that dll in your project, as George has replied.. — Mayank Pathak, Sep 12 '12 at 12:07
I've already add the dll reference in the c++ project, then what's next? — monnoliv, Sep 12 '12 at 12:13

In Visual Studio, bring up the properties of the C++/CLI project, go to "Common Properties/Framework and References" in the tree at the left, and click the "Add New Reference" button. This will bring up the standard "Add Reference" dialog you can get from a C# project, just select your C# DLL or reference a C# project in the same solution.

You need to add a reference into your project. In Visual Studio, right-click your project, then select "References".

You add reference to you assembly, Set ComVisible attribute to your assembly

Edit your AssemblyInfo.cs

[assembly: ComVisible(true)]

.Net Framework have MSIL langage in order to manage interoperability betwwen different langages
