基于WCF的消息推送服务研究与实现
本课题主要通过WCF技术实现一个企业级、跨平台的即时消息订阅与推送服务，使服务得到了统一的管理和统一的使用。WCF实现通信首先需要定义服务契约；其次，在服务端实现这些契约；最后，实现客户端。不论企业现有业务系统使用何种技术开发，都可以在不改变（或少改变）现有业务系统的情况下，将现有系统接入服务，为企业业务系统整合节省成本。7813

The research and implementation of pushing information service based on WCF
Abstract: In recent years, increasing attention real-time information, the latest information on how the server promptly notified to each terminal become a research hotspot. WCF in the .NET Framework an expansion, integration and expansion of distributed systems. . NET Framework Remoting, ASP.NET Web services, Web services enhancements and other technologies. WCF framework is based on service-oriented architecture to build loosely coupled applications, this architecture can be more safe and reliable cross-platform operation.
The main subject of the WCF technology to achieve an enterprise-wide, cross-platform instant messaging with push subscription services so that services have been unified management and unified use. WCF for communication first need to define the service contract; Secondly, in the service side to achieve these contracts; Finally, to achieve the client. Regardless of what company's existing business systems using the technology development, can not change (or little change) in the case of existing business systems, the existing system access services for the enterprise business system integration cost savings.
