I was talking with a bright guy inside the ADO.NET team today when he told me that the DbCommandBuilder supports a new option called ConflictOption. This option alerts the DbCommandBuilder to use one of three methods for detecting concurrency conflicts:
Unfortunately, the TableAdaptersin Typed DataSets (v 2.0) don’t seem to be using this when they create their concurrency (the TableAdatper code generator uses a DbCommandBuilder to create the Update/Delete statements).
Additionally, the ASP.NET 2.0 DataSources do not use DbCommandBuilders so they won’t use timestamps to do currency at all. But my rant about DataSources is for another day.
