In case you missed the news, .NET 3.5 SP1/Visual Studio 2008 SP1 were both released yesterday morning.
Bits can be found here: http://go.microsoft.com/fwlink/?LinkId=122094. Updating Visual Studio to SP1 automatically brings your .NET 3.5 install up to SP1 as well.
And for those developers who want to come up to speed on the enhancements in .NET 3.5, the training kit has been updated to work with SP1. Get it here: http://go.microsoft.com/?linkid=8719735, and take a look at Jonathan Carter's blog entry which announces the training kit re-release: http://lostintangent.com/2008/08/11/net-35-enhancements-training-kit-rtm/
In a future post, I'll take a look at the Visual Studio-specific changes made with SP1.
