| 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. |

| 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. |
