ADO.NET v.next in TechEd, and DLinq?
If you are interested in ADO.NET Entity Framework, make sure you attend to the following sessions:
DAT101 Microsoft's Data Platform Vision, Dave Campbell (I'm not actually not sure if he'll talk about it in this one, but I guess so).
DAT304 Next Generation Data Access in .NET Applications with ADO.NET vNext, Pablo Castro
There's also a Hands On Lab:
DAT013 ADO.NET Orcas: LINQ and the Entity Framework
By the way, there are no DLinQ breakout sessions in TechEd. The only 'session' on DLinQ is the DLinQ BOF.
