属性值
The original .edmx file that was loaded into memory.
备注
In a Visual Studio extension, the OriginalDocument property provides a view of the input document (as an XDocument) at the time the OnAfterModelLoaded method is called and before any methods defined in Visual Studio extensions are called. The document that is contained in this property cannot be modified.
The value of this property will be null when the OnAfterModelLoaded method loads a file that does not have an .edmx file extension.
