You may have noticed some interesting behavior when using intellisense with the Feb CTP.
One of the Microsoft Regional Directors, Juval Lowy, has put together an updated XSD that can resolve said weirdness, resulting in Feb Syntax Intellisense for the CTP.
Here's where to get it and how to install it.
(1)Download xsd file from here http://www.idesign.net/idesign/temp/dotNetConfig.zip
(2)rename current dotnet config file
(3)copy the file to C:\Program Files\Microsoft Visual Studio 8\Xml\Schemas
