In Visual Studio 2005, when you create a Typed DataSet, it automatically creates TableAdapters for you. These are interesting objects that use a DataAdapter internally to make a more cohesive data access layer. It will certainly help the RAD developers get started. I am not so sure about how they will work long-term though.
One of the more interesting things that these new Typed DataSets do is store a link to connection information in the Typed DataSet. These seems to be used for the TableAdapters to do their open’s with. Problem seems to be that if you migrate a Typed DataSet from 1.1, there is no way to insert this connection information. Even if you do, the designer in Beta 2 doesn’t allow you to attach TableAdapters to your existing Typed DataSet. This means that if you want to use TableAdapters you will need to re-do your Typed DataSets entirely.
I just finished an article talking about about some of these migration issues. I’ll post a link when it gets published.
