System.ComponentModel.Composition
Namespace
This namespace provides classes that constitute the core of the Managed Extensibility Framework, or MEF.
Classes
| AdaptationConstants |
Contains static metadata keys used by the composition system. |
| AttributedModelServices |
Contains helper methods for using the MEF attributed programming model with composition. |
| CatalogReflectionContextAttribute |
When applied to a Assembly object, enables an AssemblyCatalog object to discover custom ReflectionContext objects. |
| ChangeRejectedException |
An exception that indicates whether a part has been rejected during composition. |
| CompositionContractMismatchException |
The exception that is thrown when the underlying exported value or metadata of a Lazy<T> or Lazy<T,TMetadata> object cannot be cast to |
| CompositionError |
Represents an error that occurred during composition. |
| CompositionException |
Represents the exception that is thrown when one or more errors occur during composition in a CompositionContainer object. |
| 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. |
| ExportLifetimeContext<T> |
Holds an exported value created by an ExportFactory<T> object and a reference to a method to release that object. |
| ExportMetadataAttribute |
Specifies metadata for a type, property, field, or method marked with the ExportAttribute. |
| ImportAttribute |
Specifies that a property, field, or parameter value should be provided by the CompositionContainer.object |
| ImportCardinalityMismatchException |
The exception that is thrown when the cardinality of an import is not compatible with the cardinality of the matching exports. |
| ImportingConstructorAttribute |
Specifies which constructor should be used when creating a part. |
| ImportManyAttribute |
Specifies that a property, field, or parameter should be populated with all matching exports by the CompositionContainer object. |
| InheritedExportAttribute |
Specifies that a type provides a particular export, and that subclasses of that type will also provide that export. |
| MetadataAttributeAttribute |
Specifies that a custom attribute's properties provide metadata for exports applied to the same type, property, field, or method. |
| MetadataViewImplementationAttribute |
Specifies the type used to implement a metadata view. |
| PartCreationPolicyAttribute |
Specifies the CreationPolicy for a part. |
| PartMetadataAttribute |
Specifies metadata for a part. |
| PartNotDiscoverableAttribute |
Specifies that this type's exports won't be included in a ComposablePartCatalog. |
Interfaces
| ICompositionService |
Provides methods to satisfy imports on an existing part instance. |
| IPartImportsSatisfiedNotification |
Notifies a part when its imports have been satisfied. |
Enums
| CreationPolicy |
Specifies when and how a part will be instantiated. |
| ImportSource |
Specifies values that indicate how the MEF composition engine searches for imports. |
