说明：  并发与协调运行时(Concurrency and Coordination Runtime)是一个可以从任意.net 2.0程序语言进行访问的托管代码库。 CCR解决了面向服务应用对管理异步操作、处理并发、利用并行硬件和处理部分失败(partial failure)的需求。它使得你设计的应用的软件模块和/或组件之间可以松耦合；这样就可以让它们可以被独立的开发，而且对运行环境和其它组件的依赖降低到最小。这种方法会改变你对程序的认识，从开始设计流程到使用同一的方式处理并发、失败和隔离。
(Concurrency and Coordination Runtime (Concurrency and Coordination Runtime) is available from any. Net 2.0 programming language to access the managed code libraries. CCR addresses management of service-oriented applications asynchronous operations, dealing with concurrent use of parallel hardware and handling partial failure (partial failure) needs. It allows you to design the application software modules and/or components can be loosely coupled between This allows them to be independent of the development, and other components of the operating environment and to minimize dependence. This method will change your understanding of the process, the design process from the beginning to use the same approach to concurrency, failure and isolation.)
