You can now download the service packs for the .NET Framework:

.NET 2.0 SP1 x86
.NET SP1 x64
.NET 3.0 SP1

They were already released two days ago. I find it interesting that almost nobody seems to care about it. I mean, if you compare it with the stir that Vista SP1 has already caused . When Microsoft introduced .NET, I got the impression that in the future the underlying OS won’t play such an important role anymore. It seems that this is not going to happen any time soon.
