.NET includes complementary web service frameworks that allow enterprise applications to gain online access to critical business data. In this training course, you will program WCF, ASP.NET Web API, and SignalR web services with C# or Visual Basic to exploit each of the frameworks and maximize these technologies. These services connect isolated data to create powerful, distributed .NET applications.

You Will Learn How To

  • Create Windows Communication Foundation (WCF) services
  • Develop RESTful web services with ASP.NET Web API
  • Harness real–time web services with SignalR
  • Connect MVC, WPF, and HTML5 browser clients to .NET services
