Microsoft.Windows.Design.Metadata Namespace

Provides an attribute table for applying custom designer attributes to controls and elements.

Register your customer FeatureProvider implementations by implementing the IRegisterMetadata interface in a separate assembly dedicated to design-time metadata. Use the AttributeTableBuilder class to build an attribute table. Call the AddAttributeTable method in your Register implementation to enable your designer feature.
