IModelConversionExtension.OnAfterFileLoaded Method

Defines custom functionality for loading a file with a custom format and converting it to an .edmx format.

Namespace:  Microsoft.Data.Entity.Design.Extensibility
Assembly:  Microsoft.Data.Entity.Design.Extensibility (in Microsoft.Data.Entity.Design.Extensibility.dll)

void OnAfterFileLoaded(
	ModelConversionExtensionContext context


Type: Microsoft.Data.Entity.Design.Extensibility.ModelConversionExtensionContext
Provides file and Visual Studio project information.

In a Visual Studio extension, the OnAfterFileLoaded method is used to extend the functionality of the Entity Data Model Designer (Entity Designer). Specifically, the OnAfterFileLoaded method converts a file with a custom format to an .edmx file. 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.OnAfterModelLoaded method, the OnAfterFileLoaded method will be called before the IModelTransformExtension.OnAfterModelLoaded method.
