备注

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.
