Provides custom implementation for user-defined type (UDT) and user-defined aggregate serialization and deserialization.
Assembly: System.Data (in System.Data.dll)
Format.Native allows SQL Server to handle serialization and deserialization automatically, but the format has restrictions on the kind of types it can handle. Format.UserDefined allows user-defined types and aggregates to handle their own serialization. User-defined types and aggregates must be marked with Format.UserDefined in the SqlUserDefinedType or SqlUserDefinedAggregate attribute, and must implement the interface.
Note that even with custom serialization, the total size of each instance must be under the maximum allowed limit, currently 8000 bytes.
