備註

In a Visual Studio extension, the UpdateModelExtensionContext class is used when you want to extend the .edmx file update process of the Update Model Wizard. An instance of UpdateModelExtensionContext is passed to the IModelGenerationExtension.OnAfterModelUpdated method, which defines custom functionality of the Update Model Wizard.

For more information about extending the functionality of the ADO.NET Entity Data Model Tools, see Extending the Entity Data Model Tools and ADO.NET Entity Data Model Designer Extension Starter Kit.
