Integrate language service (MPF) and editor extension (MEF)

Does anybody the correct way to integrate a languageService (M开发者_如何转开发PF) with an editor extension (MEF) in Visual Studio 2010.

Where to implement the member completion, syntax highlight, quick info, etc.?

Any example avaliable?

Thanks!

The MSDN recommends to use the new editor API, and here there is the source code of the IronPython integration solution.

Thanks to all!
