Announcing Enterprise Library 5.0 and Unity 2.0 Roadmap

When will Enterprise Library 5 and Unity 2.0 ship? In short, on April 14, 2010.

In the meantime, we plan to release two public betas. Here’s our tentative timeline:



Please note:

1) We do not plan a 5.1 service release. 5.0 will target both Visual Studio 2010 and Visual Studio 2008. Customers have given us the feedback that this is what they prefer.

2) We will ship BETA 1 on Feb 8, 2010 which will include an msi. BETA 1 will not have all Dev10 integration features included. The new config tool will only be available to run standalone. Also, some documentation will be incomplete.

3) After the Visual Studio 2010 public Release Candidate is published, we’ll gather further input from our customers, and perform extensive integration and system testing against the RC. This will result in BETA 2 (on Mar 15, 2010) which will be feature and code complete.

4) Final Release to Web (RTW) will include a system test pass against the final Visual Studio 2010 RTM bits.

Hopefully, this information will help you plan your migration effort to the new version of Enterprise Library and Unity.

In the meantime, our most recent code drop is available at:

We look forward to your feedback, your stories of migrating to Enterprise Library 5 from previous versions or using it for the first time. Since the main theme for the release is simplicity and usability, we particularly seek comments from new users. How easy was it to get going with EntLib? What can be done to make your learning experience better?

The team has put a lot of effort into this release and we look forward to enriching your development experience with the improved reusable components, new fresh set of guides, and updated QuickStarts and code samples.

    The keyword in the roadmap is "tentative" 🙂

    We are pretty close to shipping.

    Please expect the final Release-to-Web of the Enterprise Library 5.0 pretty soon (I am talking about several days).

    Waiting for Ent Lib 5 Final.

    Any anticipated date??

  5. @Adil and all enthusiastic EntLib users

    We are as eager to get the release out as you are. Right now, we are going through the final quality gates for v5.0 and will be releasing soon (next week).
