IModelConversionExtension.OnBeforeFileSaved Method
Defines custom functionality for converting an .edmx file to a file with a custom format before the file is saved.
Assembly: Microsoft.Data.Entity.Design.Extensibility (in Microsoft.Data.Entity.Design.Extensibility.dll)
'Declaration Sub OnBeforeFileSaved ( _ context As ModelConversionExtensionContext _ ) 'Usage Dim instance As IModelConversionExtension Dim context As ModelConversionExtensionContext instance.OnBeforeFileSaved(context)
Parameters
- context
- Type: Microsoft.Data.Entity.Design.Extensibility.ModelConversionExtensionContext
Provides file and Visual Studio project information.
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.

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