Remarks
In a Visual Studio extension, use the ModelConversionExtensionContext class to enable the Entity Data Model Designer (Entity Designer) to load and save files with a custom format. An instance of ModelConversionExtensionContext is passed to the IModelConversionExtension.OnAfterFileLoaded method or the IModelConversionExtension.OnBeforeFileSaved method, which define how custom file formats will be loaded and saved.
By default, the Entity Designer loads and saves .edmx files. The IModelConversionExtension class enables the Entity Designer to load and save files that have a different format. The IModelTransformExtension class, by contrast, transforms an .edmx file before it is displayed in the Entity Designer and before it is saved. These two classes can be used together in the same Visual Studio extension.
