Visual Studio 2005 February CTP
There seems to be a fair bit of confusion around regarding the Feb release of the VS2005 CTP. It is available via the MSDN subscribers download section, however, I haven't seen it anywhere else on the web.
It was released on the 3rd of March for those who are interested :)
If you are an MSDN subscriber, you can find the latest build under Developer Tools, Visual Studio 2005.
