CUDA integration with Windows Forms/WPF

Currently I have a console application, which is fine for me, but not for others. I need to create a GUI. I am developing for Windows 7 using Visual Studio 2010 and CUDA 3.2 build customizations.

Can I simply create a GUI in Windows Forms / WPF and then just state an extern "C" function, that will be resolved to a function calling a CUDA kernel? I tried to do so just now and I had a lot of compilation errors, including some CLR stuff. After a quick googling I have the impression, that it isn't as simple as it seemed.

-- edit

The generalized question is: how to include CUDA code in C++ Windows Forms / WPF application?

If you're using Visual Studio 2010, you can get started by downloading Cuda Toolkit v4.2 and then downloading CudaFy.net. A search for each on google will get you to the correct pages. Then you make sure nvcc is running. It is necessary to compile C# code into low level (cuda) code. You can then download sample apps to test how they work. You can start here

My partner and I had the same problem. We decided to write GUI in C# Windows Forms because of simplicity. However, we couldn't find any way of using CUDA in the same project (not even for Managed C++). There might be some way of doing it, but here is our solution: we created another project which was written in native c++ and produced dll file. Then, we used P/Invoke (Platform Invoke) in C# so, that we could call exported functions from dll. In the dll, there should be kernel and some device functions, but you should create another function which calls kernel and which will be exported. You can google P/Invoke and find out how to import native c++ functions from dll to c# application.
