We have released version 2.1.1 of the Health Connection Engine to CodePlex.
The release addresses a few issues we identified in setup and the Deployment Guide and some security and performance warning raised by FxCop.
From the project description: "The Health Connection Engine facilitates the interoperability between these multiple systems by abstracting the interfaces used to connect them and by providing a rich and extensible adapter framework."
As usual we welcome any feedback you might have on HCE.
We're thinking about the next version and the two topics that came up in our heads are support for WCF and integration with the Microsoft ESB Guidance.
What do you think?
