Starts the loading process.
Assembly: System.Design (in System.Design.dll)
This is an implementation of the abstract DesignerLoader.BeginLoad method. You do not need to override this method in your own class. The method performs the following actions:
It verifies that the design surface has not already loaded.
On the first call, it adds relevant services and calls the Initialize method.
If the designer loader service has not been removed from the service container, will call the IDesignerLoaderService.AddLoadDependency and IDesignerLoaderService.DependentLoadComplete methods instead of the OnBeginLoad and OnEndLoad methods. In this situation, it is the responsibility of the designer loader service to call OnBeginLoad and OnEndLoad.
