Changes have been announced to both the naming of "special" directories (i.e. resources, data, bin ... ) and the compilation model of Asp.net in beta 2 of vs 2005. [0]
Personally I would have preferred a single root for the 'special'-directories, which has been considered, but rejected.
The single root approach was rejected because it did not enable us to support directories located in arbitrary locations in the application tree, such as the local resources directory.
The default compilation model is changed to keep the markup outside of the compiled binaries. I'm not sure what to think if it, but certainly during development it's a lot easier to work with.
