Question

Do all versions of Windows 7 include version 3.5 of the .NET Framework?

Answer 1

Wikipedia says that 3.0 is installed in Windows 7. I thought 3.5 was on it though...

I think Wikipedia isn't correct. If you look at the .NET 3.5 SP1 download page, it doesn't list Windows 7 as a supported operating system. I think that's because it's included with Win7. Also makes sense because 3.5 SP1 was released 11/18/2008, and Win7 was released almost a year later.
