Visual Studio 2008 SP1 released
Some stuff it includes:
- Some new WPF designer stuff (not sure what though - not really my area)
- ADO.NET Entity Designer
- Office MFC stuff (not sure if it also includes TR1, these two were bundled together earlier on in the year)
- Background compilation for C#
Also you will need SP1 to use VS2008 with SQL Server 2008 which was released a few days ago.
