Brian Heineman wrote a doclet to convert Javadoc into .NET XML documentation that can be consumed by .NET tools like Visual Studio. This makes the type and member documentation available in the Visual Studio IntelliSense popups. Very nice! There's still room for improvement, especially in the area of converting broken html tags into well formed xml tags. The code is available cvs. I've used it to generate an xml documentation file for IKVM.OpenJDK.ClassLibrary.dll and that can be downloaded here.
In future IKVM releases I plan to include an ikvmc compiled version of IKVMDoc.
Gena Donchyts wrote a handy tool that analyzes a bunch of jars and generates a script to ikvmc compile these jars in the right order and with the required (static) dependencies. The tool and documentation are available here.
Thanks to Brian and Gena for providing these great tools!
