Provides functionality that enables the Business Data Connectivity (BDC) service runtime to get and set the values of fields in data structures that represent External Items.
Assembly: Microsoft.BusinessData (in Microsoft.BusinessData.dll)
This interface can be implemented by the data types in assemblies for the .NET Assembly connector. By default, BDC will use reflection to access the property values on the data structures. However, this method is often slow. Implementing this interface and providing a fast way of accessing the property values will improve the performance of your application.
