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

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

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

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.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
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.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnChanged(ComposablePartCatalogChangeEventArgs)	Raises the Changed event.
OnChanging(ComposablePartCatalogChangeEventArgs)	Raises the Changing event.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Events

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

IEnumerable.GetEnumerator()

Returns an enumerator that iterates through the catalog. (Inherited from ComposablePartCatalog)
