I'm using the Enterprise Library Data Access Application Block in order to use a variety of different databases on the backend without changing my code. One thing that recently came up was how to properly use a TIMESTAMP field in MSSQL. I don't want to use SqlDbType.Timestamp, as that refers to a specific DBMS implementation, and there is no DbType.Timestamp at the base class level for me. The following code snippet does work, though, so use this to get unstuck:

    db.AddOutParameter(cmd, "@newLastChanged", DbType.Binary, 8);
