The example code is available on GitHub <a href="https://github.com/zbrad/wsweb">here</a>.</p> <h1 id="background">Background</h1> <p>WebSockets were introduced as part of the draft HTML5 specification in 2008, and the first browser to provide support was Google Chrome in 2009.</p> <p>At this time (July 2016), the following browsers fully support the WebSocket standard (<a href="https://tools.ietf.org/html/rfc6455">RFC 6455</a>):</p> <ul> <li>Internet Explorer 10</li> <li>Firefox 11 (PC,Android)</li> <li>Chrome 16 (PC,Mobile)</li> <li>Safari 6 (Mac,iOS)</li> <li>Opera 12.10 (PC,Mobile)</li> <li>Android Browser 4.4</li> </ul> <h2 id="websockets">Websockets</h2> <p>Unlike the HTTP protocol, a WebSocket provides fully bi-directional (full-duplex) communication, enabling a event based model of programming using a message passing protocol. Since there is not the constant overhead of re-establishing the connection, the passing of multiple small messages is extremely efficient and lends itself well to client/service interactions with low latency.</p>https://zbrad.github.io/tools/WcfLib/Mon, 19 Oct 2015 00:00:00 -0700https://zbrad.github.io/tools/WcfLib/<p>Describes the <a href="https://github.com/zbrad/WcfLib">WcfLib</a> component, for easily creating Wcf services, clients, and routers. These are useful for creating and communicating with WCF services, particularly in Azure environments which require WCF routing capabilities. Available as a (<a href="https://www.nuget.org/packages/ZBrad.WcfLib/">WcfLib NuGet Library</a>)</p> <h2 id="background">Background</h2> <p>I&rsquo;ve been working with a customer who was looking to re-host one of their existing applications in the <a href="https://azure.microsoft.com/en-us/campaigns/service-fabric/">Microsoft Azure Service Fabric</a> environment.</p> <p>This particular application uses <a href="https://msdn.microsoft.com/en-us/library/ms731082(v=vs.110).aspx">Windows Communication Foundation (WCF)</a> framework for communication between clients and services. However when hosting applications in Azure Service Fabric, clients typically do not directly connect to services, but utilize a router or gateway to talk to the services (see next article on a Fabric router).</p>
