备注

In a Visual Studio extension, the ModelGenerationExtensionContext class is used when you want to extend the .edmx file generation process of the Entity Data Model Wizard. An instance of the ModelGenerationExtensionContext class is passed to the IModelGenerationExtension.OnAfterModelGenerated method, which defines custom .edmx file generation functionality of the 实体数据模型 Wizard.
