설명

In a Visual Studio extension, the OnBeforeFileSaved method is used to extend the functionality of the Entity Data Model Designer (Entity Designer). Specifically, the OnBeforeFileSaved method converts an .edmx file to a custom format before the file is saved. The Microsoft.Data.Entity.Design.Extensibility.ModelFileExtensionAttribute is used to annotate classes that implement the IModelConversionExtension interface. The Microsoft.Data.Entity.Design.Extensibility.ModelFileExtensionAttribute constructor accepts a string parameter that specifies the file extension for custom files that can be loaded and saved by the Entity Designer.

참고:
When building a Visual Studio extension that also implements the IModelTransformExtension.OnBeforeModelSaved method, the OnBeforeFileSaved method will be called after the IModelTransformExtension.OnBeforeModelSaved method.
