The official source of information on Managed Providers, DataSet & Entity Framework from Microsoft
We have just updated a number of Entity Framework samples, including two sample providers, to work with the .NET Framework 3.5 and Visual Studio 2008 SP1 released today. Most updates were cosmetic, but there are some major changes too.
Check back as we continue to update the remainder of our Entity Framework samples over the coming weeks.
