WCF interview questions: - What is WCF REST?

Before we define WCF REST, lets define REST. REST is an architectural style built on certain principles using the current “Web” fundamentals.

It has five important principle: -

• Everything is a resource.
• Every resource is identified by a unique identifier
• Use simple and uniform interfaces.
• Communication are done by representation.
• Be Stateless.

To implement WCF REST we need to use first enable webhttp bindings in behavior as shown in the below code snippet: -

 <endpointBehaviors>

        <behavior name="NewBehavior0">

          <webHttp />

        </behavior>

</endpointBehaviors>

We can then use WebGet or WebInvoke to ensure that our URL is invoked by using HTTP POST or GET: -

[OperationContract]

[WebGet(UriTemplate = "/Students/{id}")]

string getStudents(string id);
