DesignerLoader can be implemented to support custom loading of a designer and designer components. A designer loader is also responsible for writing changes to an open document back to the storage the loader used when loading the document after the Flush method is called.

By default, the Visual Studio .NET development environment creates its own variety of DesignerLoader that can load basic designer projects. To create a custom designer loader, you must inherit from and implement the abstract DesignerLoader class. You cannot directly instantiate DesignerLoader, as it has no public constructor.

When BeginLoad is invoked, the designer loader loads the design document, displays the designer surface using the IDesignerHost interface, and calls EndLoad on the IDesignerLoaderHost interface when done. The IDesignerLoaderHost implementation is usually the same class that implements IDesignerHost.
