Online .NET Framework Object Browser (sort of)

Its sort of a namespace/class hierarchy viewer for the .NET base class library. Here's the link for framework v1.1:

and here's the link for framework v2.0 beta:
http://www.vb2themax.com/dotnetbrowser/showassemblies.aspx

Its pretty good - its also got a search feature (haven't tried it out though). The good thing for v2.0 beta is that it lists what is new in v2.0, what has changed since v1.1, what has been deprecated from v1.1, etc. That should definitely save some time for people moving from v1.1 to v2.0. Check them out..
