When speaking about or demoing EntLib, I often get asked which Microsoft products Enterprise Library is used in. There are several dozen internal Microsoft projects (that we know of) that take advantage of Enterprise Library. However, many people are particularly interested in commercial products that use it. Today I am able to speak about some of them.

This Monday the Microsoft Exchange team announced the public launch of Exchange Server 2010. There are many innovations in it, which you can read about on the Microsoft Exchange Teamblog. The reason I mention it here, however, is not only to congratulate the Exchange team, but also to proudly share the news that Enterprise Library and Unity container are used by Exchange Server 2010.

In addition, the Enterprise Service Bus (ESB) Toolkit 2.0, which is now part of Microsoft BizTalk Server 2009 also uses Enterprise Library 4.1 and Unity 1.2

Through the course of my interactions with many customers, I’ve compiled an extensive list of companies that use Enterprise Library (including 50 Fortune 500 companies). Unfortunately, I do not have permission to share many of their names. However, you can find some of the case studies published here. In addition, you can explore Microsoft Solution Finder and search for projects with “Enterprise Library” as a keyword.

These endorsements are a clear indication of the value that Enterprise Library provides to Microsoft product groups, our customers and partners.

I would also like to use this opportunity to invite customers who would like to share their story, and be profiled on our patterns & practices development center page, to contact me.
