The object in the 4ccd7ad6-b934-4f7c-82a0-cfd2d4a95faf Entity Data Model Designer or the 94e836e8-a5ea-47ff-aa3e-599d8a02ebfd Model Browser that, when selected by a user, triggers the call of the CreateProperty method.
备注
In a Visual Studio extension, the EntityDesignerExtendedPropertyAttribute is used when extending the functionality of the Entity Data Model Designer (Entity Designer). Specifically, the EntityDesignerExtendedPropertyAttribute is used to annotate classes that implement the IEntityDesignerExtendedProperty interface. The EntityDesignerExtendedPropertyAttribute constructor accepts a parameter of type EntityDesignerSelection that specifies which objects, when selected in the Entity Data Model Designer or the Model Browser, cause the CreateProperty method of the annotated class to be called.
For more information about extending the functionality of the ADO.NET Entity Data Model Tools, see Extending the Entity Data Model Tools and ADO.NET Entity Data Model Designer Extension Starter Kit.
