VS 2008 and .NET 3.5 has finally shipped... All the goodness is out of the beta phase :)
To get a rundown of the new features take a look at Scottgu's post
"If you are a MSDN subscriber, you can download your copy from the MSDN subscription site (note: some of the builds are just finishing being uploaded now - so check back later during the day if you don't see it yet).
If you are a non-MSDN subscriber, you can download a 90-day free trial edition of Visual Studio 2008 Team Suite here. A 90-day trial edition of Visual Studio 2008 Professional (which will be a slightly smaller download) will be available next week. A 90-day free trial edition of Team Foundation Server can also be downloaded here.
If you want to use the free Visual Studio 2008 Express editions (which are much smaller and totally free), you can download them here.
If you want to just install the .NET Framework 3.5 runtime, you can download it here."
