[Microsoft] Sandcastle produces accurate, MSDN style, comprehensive documentation by reflecting over the source assemblies and optionally integrating XML Documentation Comments. Sandcastle has the following key features: Works with or without authored comments, Supports Generics and .NET Framework 2.0, Sandcastle has 2 main components (MrefBuilder and Build Assembler), MrefBuilder generates reflection xml file for Build Assembler, Build Assembler includes syntax generation, transformation..etc, Sandcastle is used internally to build .Net Framework documentation.

Interesting. I was pleasantly surprised to see that Sandcastle was released to the public (it’s been internally used for a while). Anyways, check it out if you need to automatically generate MSDN style documentation for your .NET code (similar to what NDOC does).
