public class ApplicationCatalog : ComposablePartCatalog, 

The ApplicationCatalog type exposes the following members.

Public methodApplicationCatalog()Initializes a new instance of the ApplicationCatalog class.
Public methodApplicationCatalog(ICompositionElement)Initializes a new instance of the ApplicationCatalog class by using the specified source for parts.
Public methodApplicationCatalog(ReflectionContext)Initializes a new instance of the ApplicationCatalog class by using the specified reflection context.
Public methodApplicationCatalog(ReflectionContext, ICompositionElement)Initializes a new instance of the ApplicationCatalog class by using the specified reflection context and source for parts.

Public propertyPartsGets the part definitions that are contained in the catalog. (Inherited from ComposablePartCatalog.)

Public methodDispose()Releases all resources used by the ComposablePartCatalog. (Inherited from ComposablePartCatalog.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the DirectoryCatalog and optionally releases the managed resources. (Overrides ComposablePartCatalog.Dispose(Boolean).)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorReturns an enumerator that iterates through the collection. (Overrides ComposablePartCatalog.GetEnumerator().)
Public methodGetExportsGets the export definitions that match the constraint expressed by the specified import definition. (Overrides ComposablePartCatalog.GetExports(ImportDefinition).)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringRetrieves a string representation of the application catalog. (Overrides Object.ToString().)

Public Extension MethodCreateCompositionServiceCreates a new composition service by using the specified catalog as a source for exports. (Defined by CatalogExtensions.)
Public Extension MethodFilterFilters the specified catalog with the specified filter function. (Defined by ScopingExtensions.)

Explicit interface implemetationPrivate propertyICompositionElement.DisplayNameGets the display name of the application catalog.
Explicit interface implemetationPrivate propertyICompositionElement.OriginGets the composition element from which the application catalog originated.
Explicit interface implemetationPrivate methodIEnumerable.GetEnumeratorReturns an enumerator that iterates through the catalog. (Inherited from ComposablePartCatalog.)

Important noteImportant

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.
