.NET Web Services Training: WCF, Web API and SignalR

.NET includes complimentary web service frameworks that allow enterprise applications to gain online access to critical business data. In this .NET Web Services 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.
