Is Coin compatible with .NET?

The Coin3D libraries are written in C and C++. The supported compilers in the Visual Studio family are VisualC++ v6, VisualC++ .NET and VisualC++.NET 2003. In-house, we mostly use VC++ v6 and VC++.NET 2003.

Coin3D is currently not a .NET assembly or component, so if you'd like to use Coin3D from other languages in the VisualStudio family (C#, VB, J#), you will need to do some C++ coding first (basically add support for Managed Extensions directly, or add some new (managed) classes that act as external interfaces to Coin3D). We are probably going to make a .NET assembly of Coin3D some time, but we haven't had sufficient customer demand for it yet.
