Worked immediately and with a nice tutorial. Thank you so much!

But one problem remains: I cannot import the DLL to the C++ CLR project. Then, I tried it with a Win32-console project, but there is also the problem that I cannot call from C++ the classes and their method from the DLL. This is not explained in your link, as the project calling the DLL is a C# project. Somehow, there is a &quot;missing link&quot; - some header file or something else is required.

<div>
Yes, that is unexpected problem. I'll try to look at it and let you know if I find something. Sorry about it.

Hello!<br />
<br />
I have a Windows Frames project written in C#. Now, for demonstration purposes, I have to write a code in C++, all in .NET Framework 4.0 with Microsoft Visual Studio 2010. I have several years of experience in C/S application, partly written in C/C++, but the WinForms project is my first .NET project and with C#.<br />
<br />
To go on faster, it would be nice to use some C# classes that I have already written, like Constants, DAOs, etc., in the demo project. I found out that it is possible to have both C++ and C# code in a CLR project, but I do not know how I can access a C# class directly from a C++ class.<br />
<br />
<b>Question</b><br />
How can I access a C# class from C++ code in a CLR project? If a DLL is the solution, how can I create a DLL out of the C# classes?

How to integrate a C#-Class into a C++-Kode in a CLR project?

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
