Where is Visual Studio 2005 Express?
I belive that VS 2008 (all editions) will only work with .NET 2.0 to 3.5 just as VS 2005 (all editions) will only work with .NET 2.0. This is the reason that VS 2005 is no longer available, because its features are duplicated by VS 2008. The only difference is the solution file, so you could make a seperate solution file for VS 2008.
For Visual Studios 2005 C++ express the vcsteup.exe is available here: http://download.microsoft.com/download/8/3/a/83aad8f9-38ba-4503-b3cd-ba28c360c27b/ENU/vcsetup.exe
