Restful Services are getting more and more popular in our days and .NET developers prefer to build them through the Web API Framework, which let’s be honest it sounds right. You need to know though that WCF Framework
also provides the support for building services that can be consumed
over HTTP requests. This post will show you how easy is to create a WCF
Restful service and consume it, either from a simple browser typing the
right URL or from another application using an HttpClient.
Open Visual Studio and create a new WCF Service Application named WcfRestfulService. At this very moment, VS has created for you a WCF service using the default binding. You can test it by right clicking the Service1.svc file and view it on browser. We are going to change that service in order to be able to invoke it using HTTP requests.
Change Service1.svc to AdminLoginService.svc.cs.There is also IAdminLoginService.cs
