c# using a c++ engine
Author
I have a c++ engine, and im intrested in making some sort of mesh viewer in c#, so with my engine running inside my c# application and using the c++ code.
is this possible? how would i go about it? currently my engine compiles in to a lib (not a dll).

for my engine you mean?
to convert my managed code it is just some project options i assume?

hrmm, looks simple enough!
do i just need to set up my project to compile as a dll and the i files i create take care of the rest?

Trouble is templates. You can only define template instantiations and rename them for SWIG, since most other languages do not have a concept like templates:
Plus operators must be renamed, which is also because of 'limitations' in other languages:
Other than that it's quite a usefull tool.

Oh goodness no. You basically have to partially rewrite it.
Don't do it - terrible idea.
Using C# isn't a bad idea if you're calling your DLL-ified C++ engine. If you can pull it off, it'll probably work quite well.
The other alternative is to use a C++ windowing system, possibly through a language like Python (I recomend wxWidgets).
I wrote a managed C++ wrapper for my engine in a night and hooked it to a C# application, it's quite simple actually. You can either write it by hand or try using SWIG to generate the wrapper.
You can use P/Invoke to call functions in C++ DLLs, much like the Tao Framework makes class wrapper functions to OpenGL and SDL for use with .NET languages like C#. You can even make sequential class structures in C# to match up to the class interface you made in C++ held in the DLL.
To call a C++ function in a DLL file, you use the DLLImport attribute:
