System.Composition Namespace

Contains classes for creating and specifying export attributes, retrieving exports from a composition, configuring import attributes, and for specifying how parts interact during composition.

Classes

CompositionContext	Provides methods to retrieve exports from the composition.
CompositionContextExtensions	Adds methods to the composition context that are specific to the typed parts model.
Export<T>	A reference that allows the graph of parts associated with an exported instance to be released.
ExportAttribute	Specifies that a type, property, field, or method provides a particular export.
ExportFactory<T>	A factory that creates new instances of a part that provides the specified export.
ExportFactory<T,TMetadata>	A factory that creates new instances of a part that provides the specified export, with attached metadata.
ExportMetadataAttribute	Specifies metadata for a type, property, field, or method that is marked with the ExportAttribute attribute.
ImportAttribute	Specifies that a property or parameter value should be provided by the host container.
ImportingConstructorAttribute	Specifies which constructor should be used when creating an attributed part.
ImportManyAttribute	Specifies that a property, field, or parameter should be populated with all matching exports by the host container.
ImportMetadataConstraintAttribute	Specifies that an import requires certain metadata values.
MetadataAttributeAttribute	Specifies that a custom attribute's properties provide metadata for exports applied to the same type, property, field, or method.
OnImportsSatisfiedAttribute	Specifies that a method should be called when composition is completed.
PartMetadataAttribute	Specifies metadata for a part.
PartNotDiscoverableAttribute	Specifies that this type's exports won't be included in a catalog.
SharedAttribute	Marks the decorated part as being constrained to sharing within the specified boundary.
SharingBoundaryAttribute	When applied to an import of an ExportFactory<T> object, marks the boundary of a sharing scope.
