	Dispose(Boolean)	Releases the unmanaged resources used by the AggregateExportProvider class and optionally releases the managed resources.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetExport<T>()	Returns the export with the contract name derived from the specified type parameter. If there is not exactly one matching export, an exception is thrown. (Inherited from ExportProvider.)
	GetExport<T>(String)	Returns the export with the specified contract name. If there is not exactly one matching export, an exception is thrown. (Inherited from ExportProvider.)
	GetExportedValue<T>()	Returns the exported object with the contract name derived from the specified type parameter. If there is not exactly one matching exported object, an exception is thrown. (Inherited from ExportProvider.)
	GetExportedValue<T>(String)	Returns the exported object with the specified contract name. If there is not exactly one matching exported object, an exception is thrown. (Inherited from ExportProvider.)
	GetExportedValueOrDefault<T>()	Gets the exported object with the contract name derived from the specified type parameter or the default value for the specified type, or throws an exception if there is more than one matching exported object. (Inherited from ExportProvider.)
	GetExportedValueOrDefault<T>(String)	Gets the exported object with the specified contract name or the default value for the specified type, or throws an exception if there is more than one matching exported object. (Inherited from ExportProvider.)
	GetExportedValues<T>()	Gets all the exported objects with the contract name derived from the specified type parameter. (Inherited from ExportProvider.)
	GetExportedValues<T>(String)	Gets all the exported objects with the specified contract name. (Inherited from ExportProvider.)
	GetExports(ImportDefinition)	Gets all exports that match the conditions of the specified import definition. (Inherited from ExportProvider.)

	GetExports(Type, Type, String)	Gets all the exports with the specified contract name. (Inherited from ExportProvider.)
	GetExports<T>()	Gets all the exports with the contract name derived from the specified type parameter. (Inherited from ExportProvider.)
	GetExports<T>(String)	Gets all the exports with the specified contract name. (Inherited from ExportProvider.)
	GetExportsCore	Gets all the exports that match the conditions of the specified import. (Overrides ExportProvider.GetExportsCore(ImportDefinition, AtomicComposition).)
	GetHashCode	Serves as a hash function for a particular type. (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.)
	OnExportsChanged	Raises the ExportsChanged event. (Inherited from ExportProvider.)
