The Microsoft Enterprise Library is a set of tools and programming libraries for the Microsoft .NET Framework. It provides APIs to facilitate proven practices in core areas of programming including data access, logging, exception handling and others. Enterprise Library is provided as pluggable binaries and source code, which can be freely used and customized by developers for their own purposes. It also ships with test cases and quickstarts.

Benefits

Application Blocks

Each application block addresses a specific cross-cutting concern and provides highly configurable features, which results in higher developer productivity. The Application Blocks in Enterprise Library are designed to be as agnostic as possible to the application architecture, for example the Logging Application Block may be used equally in a web, smart client or service-oriented application.

The patterns & practices team produces a number of other deliverables that leverage Enterprise Library Application Blocks. These include the Web Service Software Factory and Smart Client Software Factory.

Utilities

In addition to the Application Blocks, the standard Microsoft distribution of the Enterprise Library includes:

Version 3.0

In April 2007, Enterprise Library 3.0 was released.

The 3.0 release of Enterprise Library contains the following Application Blocks:

Version 2.0

In January 2006, a new version of Enterprise Library was released that targeted .NET Framework 2.0. The most significant change in this release was that the Configuration Application Block was removed, and the blocks were updated to use .NET's improved System.Configuration capabilities. This release also included significant improvements to the Logging Application Block, and much of the Security Application Block was removed due to similar capabilities provided in .NET Framework 2.0. The .NET 2.0 release of Enterprise Library contained the following Application Blocks:

Version 1.1

Two releases of Enterprise Library were released for .NET Framework 1.1. The first was released in January 2005, followed by a minor maintenance release in June 2005. The .NET 1.1 releases of Enterprise Library contained the following Application Blocks:

Future

Ron Jacobs, a Microsoft Evangelist, described the purpose of Enterprise Library as "filling in the gaps" of .NET development between releases of the framework. As the framework continues to advance, developers are demanding more productive development libraries.

At the same time, Microsoft platforms evolve and certain scenarios, initially addressed by the Enterprise Library, are now being supported by the platforms themselves. In this case, the patterns & practices team uses the graceful retirement process to deprecate some parts as explained here.

Microsoft continues to promote Enterprise Library for enterprise/line-of-business development, and even many Microsoft products as well as projects within Microsoft IT use it extensively.

Starting November 2013, Microsoft fully opensourced Enterprise Library and all of its application blocks. They now accept community contributions. The latest releases of SLAB1.1 and Unity3.5 are developed in close collaboration with the community.

In August 2015, Microsoft posted[1] they were handing Unity Dependency Injection over to new owners (Pablo Cibraro and Pedro Wood) into a new GitHub repo. At the same time, the patterns & practices - Enterprise Library home web site on CodePlex,[2] announced that the remainder of the application blocks will no longer be developed. However, the source will continue to be available.
