Enterprise Library is a collection of reusable software components (application blocks) designed to assist software developers with common enterprise development challenges (such as logging, validation, caching, exception handling, and many others). Application blocks are a type of guidance encapsulating Microsoft recommended development practices; they are provided as source code plus documentation that can be used "as is," extended, or modified by developers to use on complex, enterprise-level line-of-business development projects.

What's New in v4.0?

This release of Enterprise Library includes the following:

– Integration with the Unity Application Block

– Windows Management Instrumentation (WMI) 2.0 support and improved instrumentation

– Performance improvements (particularly, in the Logging Application Block)

– Pluggable Cache Managers

– Visual Studio 2008 support

– Bug fixes

Note: existing public APIs (v3.1) are still supported.

The Application Block Software Factory and the Strong Naming Guidance Package are not included in this release but are available as a separate download. Thus, there is no longer a dependency on Guidance Automation Extensions (GAX).

For the detailed list of all changes, see About This Release of Enterprise Library.
