Enterprise Library 4.1 + Unity Application Block 1.2 December 2008

微软Patterns&Practices发布了Enterprise Library 4.1。Enterprise Library是一个可重用的组件（application blocks）集，它利用企业开发中常见的一些功能（如日志、验证、缓存、异常处理等）来辅助软件开发者。Application blocks是一种指导方针，封装了微软推荐的开发实践。

该发布还带有一些快速上手示例、手把手的试验、关于Enterprise Library和Unity的Webcasts及示例代码。

该发布中的一些关键性的增强都与Unity Application Block 1.2相关。Unity Application Block（Unity）是一个轻量级、可扩展的依赖注入/控制反转（IOC）容器。Unity application block还以独立库的形式发布。正如上面所指出的，该库的一些改进都围绕着对泛型、数组和性能的更好支持而展开。

Unity的发布中还带有一些快速上手示例及Webcasts，对使用Unity进行依赖注入进行了介绍并谈到了如何扩展Unity的依赖注入容器。该项目的源码位于www.codeplex.com/unity，同时还有一个Codeplex项目供社区进行扩展。

What is Unity?

The Unity Application Block (Unity) is a lightweight, extensible dependency injection container. This release of Unity is a port of Unity Application Block 1.2 to Microsoft Silverlight 2.0.

What’s New?

The following capabilities and packaging of the Unity container have been adjusted in this release:

–                     The single Microsoft.Practices.Unity.dll file in the Silverlight version contains all the classes from the three separate desktop DLLs:

        Microsoft.Practices.Unity.dll, 

        Microsoft.Practices.ObjectBuilder2.dll,

                     Microsoft.Practices.Unity.StaticFactoryExtension.dll.

                You only need to reference and deploy the one assembly in your Silverlight projects.

–                     Because of differences in the Silverlight security model, only public types can be created and injected by the container. The desktop version allows you to also inject internal types.

–                     XML configuration is not supported.

–                     The Unity interception mechanism is not supported.

An updated quickstart is also included.
