Specifies a class that will add extra attributes to the metadata store.

Namespace:   System.Activities.Presentation.Metadata
Assembly:  System.Activities.Presentation (in System.Activities.Presentation.dll)

public interface IRegisterMetadata


Adds additional metadata to the metadata store upon initialization of the designer.

IRegisterMetadata types provide a way to encapsulate the association of design-time attributes to run-time types in a loosely coupled fashion. An application hosting the Windows Workflow Designer can use the IRegisterMetadata interface to register the attributes for the activity. For instance, Visual Studio 2010 searches for types that implement IRegisterMetadata when assemblies that contain these types are loaded in addition to also looking for types in the *.design assemblies.
