Remarks

Important

This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

Constructors

Name	Description
CompositionScopeDefinition()	Initializes a new instance of the CompositionScopeDefinition class.
CompositionScopeDefinition(ComposablePartCatalog, IEnumerable<CompositionScopeDefinition>, IEnumerable<ExportDefinition>)	Initializes a new instance of the CompositionScopeDefinition class with the specified underlying catalog, children, and public surface.
CompositionScopeDefinition(ComposablePartCatalog, IEnumerable<CompositionScopeDefinition>)	Initializes a new instance of the CompositionScopeDefinition class with the specified underlying catalog and children.

Properties

Name	Description
Children	Gets the child scopes of this catalog.
Parts	Gets the part definitions that are contained in the catalog. (Inherited from ComposablePartCatalog)
PublicSurface	Gets a collection of parts visible to the parent scope of this catalog.

Methods

Name	Description
Dispose()	Releases all resources used by the ComposablePartCatalog. (Inherited from ComposablePartCatalog)
Dispose(Boolean)	Called by the Dispose() and Finalize() methods to release the managed and unmanaged resources used by the current instance of the CompositionScopeDefinition class.
GetEnumerator()	Returns an enumerator that iterates through the catalog.
GetExports(ImportDefinition)	Gets a collection of exports that match the conditions specified by the import definition.
OnChanged(ComposablePartCatalogChangeEventArgs)	Raises the Changed event.
OnChanging(ComposablePartCatalogChangeEventArgs)	Raises the Changing event.

Events

Name	Description
Changed	Occurs when the underlying catalog has changed, if that catalog supports notifications.
Changing	Occurs when the underlying catalog is changing, if that catalog supports notifications.

Explicit Interface Implementations

Name	Description
