Enterprise Library 5 and Unity 2 Beta are now available for evaluation. This is a major release for us in patterns & practices – and with the exception of Visual Studio integration, is now feature complete.

We are very excited about the enhancements we’ve made to the architecture and the configuration experience, both of Enterprise Library and Unity.

The team has put a lot of effort into the testing of this release – but, this is work in progress; more platform, performance, and accessibility testing as well as end-to-end scenario testing is in progress, before the final release..

Very shortly, we will be providing a migration guide that will help you to migrate from previous versions of Enterprise Library to version 5.0. We will also be updating the hands-on-labs as well for this version.

If you are new to Enterprise Library, consider reading the new Developer Guide  - and please let us know your feedback.
