I am now a member of the EntLib Contrib project and have created the Extended SQL Data Access Block.
This data access application block extends the SQL Data Access Block provided by Enterprise Library. It provides additional overloads for the UpdateDataSet method so that a collection of rows or a table can be passed to the DataAdapter for update. These methods were developed to support updating datasets that have multiple tables and cascading hierarchies.
For more information goto Extended SQL Data Access Block.
For the latest release goto Extended SQL Data Access Block 3.1
