Exposes methods for extending the loading and saving processes of .edmx files.
Assembly: Microsoft.Data.Entity.Design.Extensibility (in Microsoft.Data.Entity.Design.Extensibility.dll)
The interface exposes methods for extending the functionality of the Entity Data Model Designer (Entity Designer). Specifically, the OnAfterModelLoaded method allows you to customize an .edmx file after it has been loaded but before it has been displayed in the Entity Designer. The OnBeforeModelSaved method allows you to customize an .edmx file before it is saved. Note that the scope of these methods is limited to modifying .edmx files. To load and save files with a custom format, see IModelConversionExtension.
