An Overview of NMS
The NMS API (.Net Message Service API) providers a standard .NET interface to Messaging Systems. There could be multiple implementations to different providers (including MSMQ). The NMS API This allows you to build .NET applications in C#, VB, or any other .NET language, using a single API to connect to multiple different providers using a JMS style API.
NMS API currently supports all of the features of JMS in a simple pure C# API and implementation apart from XA. Current features include
- creating & disposing of connections, sessions, producers, consumers
- sending of messages to topics, queues with durable or non durable along with temporary destination support
- synchronous consuming (blocking receive, receive with no wait or receive with a timeout)
- asynchronous consuming (adding a MessageListener to be dispatched in the thread pool)
- message header support along with custom properties
- Text, Bytes, Stream and Map message support
- support for transactions (sending and acknowledging multiple messages in an atomic transaction)
- redelivery of messages in rollbacks up to some configured maximum redelivery count
- Optional Queue browser interface for providers that can support it.
- Optional .NET Distributed Transaction Support for providers that can support that.
A provider implementation based on a pure C# implementation of OpenWire is provided for working with the Apache ActiveMQ broker. There are other provider implementations for working with Stomp, TIBCO, Microsoft Message Queue (MSMQ), and Windows Communication Foundation (WCF).
If you are curious you can browse the source code and tests for the entire project or download an NMS Provider.
