Heathcliff74, a member over at the XDA Developers forum, has published an in-depth tutorial for developers who may wish to improve homebrew apps using native Mango code. It's a step-by-step guide that will enable homebrew apps take full advantage of native Mango code and APIs.

While this tutorial has been available since October 11th, it's worth mentioning after the release of the homebrew screen capture utility. Note that this isn't a tutorial for building homebrew executables, but how to utilise native code DLLs from within the Silverlight app.
