Microsoft has released the .NET Framework 3.5 SP1 and Visual Studio 2008 SP1 this week to Microsoft Downloads only a few days after releasing SQL Server 2008.
Two of the main features added in the .NET Framework service is pack is the ADO.NET Data Services and the ADO.NET Entity Framework. Visual Studio 2008 Service Pack 1 comes with a better WPF designer, a rich entity designer and full compatibility with SQL Server 2008 that was released a few days ago.
Thanks to by buddy John Oswalt for keeping me in the loop.
