v2: Implementing c++ interface callback in C#

[@lx]

Hi all,
I have just released the code to implement the C++ interface callback
in C# for SlimDX2. I have slightly modified the generator in order to
generate empty interfaces for interfaces callback.

You can have a look at an example of implementation here for the
ID3DInclude interface :
http://code.google.com/p/slimdx/source/browse/branches/v2/SlimDX2/Sources/SlimDX2.D3DCompiler/Extension/Include.cs

I have just posted an article on my blog about it :
http://code4k.blogspot.com/2010/10/implementing-unmanaged-c-interface.html

This demonstrate where we still need to handle some code manually
after the generator, although you can see that It's fairly simple and
straightforward. Because there are not so many callbacks to implement,
they will be probably implemented like this.

You have a small bug:

http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marshal.getfunctionpointerfordelegate.aspx

You must manually keep the delegate from being collected by the garbage collector from managed code. The garbage collector does not track reference to unmanaged code.

You'll need to host the delegates permanently inside the IncludeCallback class.
