Assembly: System.Messaging (in system.messaging.dll)
When an application sends a message to the queue using an instance of the MessageQueue class, the formatter serializes the object (which can be an instance of any class) into a stream and inserts it into the message body. When reading from a queue using a MessageQueue, the formatter deserializes the message data into the Body property of a Message.
BinaryMessageFormatter and ActiveXMessageFormatter provide faster throughput than the XmlMessageFormatter. The ActiveXMessageFormatter allows interoperability with Visual Basic 6.0 Message Queuing applications. The XmlMessageFormatter is loosely coupled, which means that the server and client can version the type that is sent and received independently.
