Microsoft released the source for Oxite, their blogging engine that's intended to help .NET developers learn ASP.NET MVC. They also released the source for the Mix site, which was built with Oxite.
Microsoft says that developers can build applications with Oxite, since it has a lot of built-in features like trackbacks, pingbacks, and RSS support.
Are you going to use Oxite to learn ASP.NET MVC? Do you think you could do anything useful with it?
I would stay away from it. It's a very bad example. I don't understand why microsoft put it on internet. First of all the security reasons, but the code is very hard to read for new developers. I use asp.net mvc since preview 2, but it's still very difficult to read that code because it's bad. Many better examples are found or used here on stack overflow. Personally I suggest watching the screencasts on Rob Connery's website or on Autumnofagile
Karl Seguin took the time to sum it all up
Rob Connery works for Microsoft and doesn't like it either
A new word is named after it: Oxitis
