.NET 3.0 "wraps" .NET 2.0 so if I'm starting out with a clean Windows Server 2003 environment, will the .NET 3.0 SP1 installer also install .NET 2.0 and 3.0? What about .NET 2.0 SP1? Assume I don't want to install .NET 3.5 SP1 just yet.

A: 

If you mean Microsoft .NET Framework 3.0 Service Pack 1 , I don't think so. However, it's supposed to be backwards-compatible, more or less.

The .NET 3.0 installer does install .NET 2.0 - the difference is in libraries only; the runtime under .NET 3.0 is still v2, though with some minor-ish patches.

The runtime under .NET 3.5 is still v2 as well - all the stuff that's new in .NET 3.5 is a mix of compiler magic and some funky libraries.

FWIW, The next version of the .NET runtime is going to be 4.0 - there won't be a v3.

You should just install .NET 3.5 SP1, and you'll get .NET 2.0 SP1 and SP2, as well as .NET 3.0 SP1 and SP2.

slight correction. .net 3.5 sp1 includes sp2 for .net 3.0 also

Thanks. I've corrected that. It was 3.5 RTM that had 3.0 SP1?
John Saunders
yes that is correct
