"SignalR: Real-time Application Development" 是一本面向.NET开发者的技术书籍,由Einar Ingebrigtsen撰写,旨在介绍如何利用SignalR框架进行实时应用程序开发。这本书提供了从基础到高级的实践指导,帮助读者将实时功能轻松集成到.NET应用中,同时涵盖了云准备和可扩展性等进阶主题,以实现企业级应用的构建。 SignalR是.NET平台上的一个开源库,专门用于简化实时Web通信。它使得服务器能够向连接的客户端推送内容,而无需客户端频繁轮询。这个框架支持多种浏览器和服务器平台,包括ASP.NET,允许开发者创建实时双向通信的应用,如聊天应用、协作工具和实时仪表板。 本书内容分为多个部分,首先会介绍SignalR的基本概念,包括安装和配置,以及如何在项目中设置基本的实时连接。然后,通过实例演示如何在客户端和服务器之间发送和接收消息,理解Heartbeat机制以保持连接,以及处理连接生命周期的管理。 随着深入,书中会讨论更高级的主题,如Hubs,这是一个强大的特性,允许开发者定义服务器端的方法,这些方法可以直接由客户端调用,反之亦然。此外,还会涉及如何使用Groups功能来分发消息给特定的用户组,实现更精细的消息控制。 在确保应用云就绪和可扩展性方面,书中的章节会涵盖如何在Azure等云平台上部署SignalR应用,以及如何优化和扩展服务以应对高并发场景。这可能包括负载均衡、信号R服务的伸缩性和持久连接的管理。 最后,书中还可能探讨了错误处理、性能监控和调试技巧,以确保在实际开发过程中遇到问题时,开发者能有适当的工具和策略来解决。 "SignalR: Real-time Application Development" 是一本全面的指南,对于希望在.NET环境中实现实时功能的开发者来说,是一份宝贵的资源。通过学习这本书,读者不仅可以掌握SignalR的基本用法,还能了解如何构建健壮、可扩展的实时应用程序,满足现代用户对即时数据需求的期望。

With technology trends, demands on software have changed with more and more skilled users. Over the past few years, with services such as Facebook, Twitter and push notifications on smartphones, users are now getting used to being up to date with everything that happens all the time. With SignalR, the applications stay connected and will generate notifications when something happens either from the system or by other users thus giving new opportunities to enter into this new, exciting world of real-time application development. This is a step-by-step guide that follows a practical approach helping you as a developer getting to get started with SignalR by learning its fundamentals. It will help you through building real-time applications using the new methods and functions in the SignalR framework. Starting from getting persistent connections with the server, you will learn the basics of connecting a client to the server and how the messaging works. This will be followed by setting up a hub on the server and consuming it from a JavaScript client. Next you will be taught how you can group connections together to send messages. We will then go on to know how you can have state in the client to handle specific operations like connecting or disconnecting. Then, moving on you will learn how to secure your SignalR connections using OWIN and scaling SignalR across multiple servers. Next you will learn building a client for WPF and building a client using Xamarin that targets Windows Phone, iPhone and Android. Lastly, you will learn how to monitor the traffic in SignalR using Fiddler, Charles and hosting SignalR using OWIN.
