Rajith’s Column

Since joining the Apache Qpid project around Nov 2008 Microsoft has been helping with the windows port of the C++ broker. They also worked on a WCF client based on the C++ client libraries. Recently (about 2 weeks back) they contributed the code (QPID-2065). The examples could be found here.

From the read me the following features are available,
1. WCF service model programming using one way contracts
2. WCF channel model programming using IInputChannel and IOutputChannel based factories
3. Programmatic access to AMQP message properties on WCF messages
4. AMQP version 0-10 (as provided by the Qpid C++ native client library)
5. Shared connections for multiple channels based on binding parameters
6. WCF to WCF applications (using SOAP message encoders)
7. WCF to non-WCF applications (using raw content encoders)
8. Rudimentary AMQP type support for headers (Int and String)
9. Channel functional tests using NUnit
10. Programming samples

There are several opportunities for folks to collaborate in this area. Cliff Jansen who worked with Qpid on the code drop identified the following areas as potential areas for contributions.

From qpid/wcf/ReadMe.txt:

2. Planned features (not yet available)
=======================================

1. Full AMQP type support, including maps and arrays
2. System.Transactions integration (local and distributed with dynamic escalation)
3. Prefetch window for inbound messages
4. Shared sessions
5. Connection failover with AMQP broker clusters
6. Temporary queues
7. Broker management
8. System logging and tracing
9. CMake build system support
10. Transport and message based security

One item that I would like to add to the above list is documentation for the WCF client and it’s examples.
