UDDT classes
For our application code to interact properly with the SQL database UDDT types, certain schema information is needed in addition to the data values themselves. A set of C# classes has been created, one corresponding to each SQL UDDT. These are found in the CSI.Data.SQL.UDDT namespace.
You will see these classes used as needed throughout the application code. These are only necessary when interacting with the database. Application classes that do not interact with the database will generally use native C# datatypes.
