nDOC

nDoc generates class library documentation from .NET assemblies and the XML documentation files generated by the C# compiler.
Documentation in the past has been a truly grueling task, especially if you want it to look any good. Who needs documentation when you have good code comments?
With the introduction of XML comments in C# and nDOC, you can ensure your code comments are complete, and create great looking documentation files all in one foul swoop.
nDoc works with the XML comment file produced by the C# compiler and can output your documentation in many different formats, including MSDN style and javaDoc style. These files can be routed to compiled help files, or straight HTML.
A truly brilliant addition to any .NET programmers toolbox.
