Intel Visual Fortran 9.0 does not support VS 2005 (The .NET name has been dropped from Visual Studio for the new edition.) We are about to enter beta test for a new version that does. If you would like to participate, send me an e-mail at steve.lionel at intel.com
Our original plan had been to run a beta that overlapped Microsoft's beta, but they kept making incompatible changes so we decided to wait until the retail release.
I'm not sure what sort of "support" for .NET Framework you are looking for.
