Classes

	Class	Description
	AccessControlEntry	Specifies access rights for a trustee (user, group, or computer) to perform application-specific implementations of common tasks.
	AccessControlList	Contains a list of access control entries, specifying access rights for one or more trustees.
	ActiveXMessageFormatter	Serializes or deserializes primitive data types and other objects to or from the body of a Message Queuing message, using a format that is compatible with the MSMQ ActiveX Component.
	BinaryMessageFormatter	Serializes or deserializes an object, or an entire graph of connected objects, to or from the body of a Message Queuing message, using a binary format.
	Cursor	A Cursor is used to maintain a specific location in a MessageQueue when reading the queue's messages.
	DefaultPropertiesToSend	Specifies the default property values that will be used when sending objects other than Message instances to a message queue.
	LocalAppContextSwitches
	Message	Provides access to the properties needed to define a Message Queuing message.
	MessageEnumerator	Provides a forward-only cursor to enumerate through messages in a message queue.
	MessagePropertyFilter	Controls and selects the properties that are retrieved when peeking or receiving messages from a message queue.
	MessageQueue	Provides access to a queue on a Message Queuing server.
	MessageQueueAccessControlEntry	Specifies access rights for a trustee (user, group, or computer) to perform Message Queuing tasks.
	MessageQueueCriteria	Filters message queues when performing a query using the MessageQueue class's MessageQueue.GetPublicQueues method.
	MessageQueueEnumerator	Provides a forward-only cursor to enumerate through messages in a message queue.
	MessageQueueException	The exception that is thrown if a Microsoft Message Queuing internal error occurs.
	MessageQueueInstaller	Allows you to install and configure a queue that your application needs in order to run. This class is called by the installation utility, for example, InstallUtil.exe, when installing a MessageQueue.
	MessageQueuePermission	Allows control of code access permissions for messaging.
	MessageQueuePermissionAttribute	Allows declarative MessageQueue permission checks.
	MessageQueuePermissionEntry	Defines the smallest unit of a code access security permission set for messaging.
	MessageQueuePermissionEntryCollection	Contains a strongly typed collection of MessageQueuePermissionEntry objects.
	MessageQueueTransaction	Provides a Message Queuing internal transaction.
	MessagingDescriptionAttribute	Specifies a description for a property or event.
	PeekCompletedEventArgs	Provides data for the MessageQueue.PeekCompleted event. When your asynchronous peek operation calls an event handler, an instance of this class is passed to the handler.
	ReceiveCompletedEventArgs	Provides data for the MessageQueue.ReceiveCompleted event. When your asynchronous receive operation calls an event handler, an instance of this class is passed to the handler.
	SecurityContext	Represents the security context for a message in a queue.
	Trustee	Specifies a user account, group account, or logon session to which an access control entry applies.
	XmlMessageFormatter	Serializes and deserializes objects to or from the body of a message, using the XML format based on the XSD schema definition.

Interfaces

	Interface	Description
	IMessageFormatter	Serializes or deserializes objects from the body of a Message Queuing message.

Delegates

	Delegate	Description
	PeekCompletedEventHandler	Represents the method that will handle the MessageQueue.PeekCompleted event of a MessageQueue.
	ReceiveCompletedEventHandler	Represents the method that will handle the MessageQueue.ReceiveCompleted event of a MessageQueue.

Enumerations

	Enumeration	Description
	AccessControlEntryType	Specifies whether to allow, deny, or revoke access rights for a trustee.
	AcknowledgeTypes	Specifies the types of acknowledgment message that Message Queuing returns to the sending application.
	Acknowledgment	Specifies the result of an attempted message delivery.
	CryptographicProviderType	Specifies the cryptographic service providers available for validating digital signatures.
	EncryptionAlgorithm	Specifies the encryption algorithm used to encrypt the message body of a private message.
	EncryptionRequired	Specifies the privacy level of messages received by the queue.
	GenericAccessRights	Uses the Windows 2000 and Windows NT access format to specify a set of common access rights that Message Queuing maps to both standard and object-specific access rights for reading, writing, and executing.
	HashAlgorithm	Specifies the hash algorithm used by Message Queuing when authenticating messages.
	MessageLookupAction	Specifies a message to peek at or receive from a message queue.
	MessagePriority	Specifies the priority Message Queuing applies to a message while it is en route to a queue, and when inserting the message into the destination queue.
	MessageQueueAccessRights	Specifies a set of object-specific access rights for operations specific to Message Queuing.
	MessageQueueErrorCode	Identifies the source of an error that occurred within the Message Queuing application and generated a MessageQueueException exception.
	MessageQueuePermissionAccess	Defines access levels used by System.Messaging permission classes.
	MessageQueueTransactionStatus	Specifies the state of an internal Message Queuing transaction.
	MessageQueueTransactionType	Specifies the type of a Message Queuing transaction.
	MessageType	Identifies the type of a message. A message can be a typical Message Queuing message, a positive (arrival and read) or negative (arrival and read) acknowledgment message, or a report message.
	PeekAction	Indicates whether to peek the current message in a queue, or the next message.
	QueueAccessMode	Specifies the access mode for a MessageQueue at creation time.
	StandardAccessRights	Specifies a set of standard access rights that correspond to operations common to most types of securable objects.
	TrusteeType	Specifies the type of a trustee.
