RESTful WCF Services works by identifing the Resources & Action from Uniform Resource Identifiers (URIs).
A RESTful web service is called by a unique URI to refer a resource and HTTP verb is to define actions to the resource.
HTTP Method – Verb
GET – Fetch
PUT – Update/Insert
DELETE – Delete
POST – Append
webHttpBinding is a new WCF binding in Fx 3.5 to develop RESTful services. This does not use SOAP envelopes HTTP and HTTPS Transports. It supports XML, JSON and Binary (streams).
WebServiceHost is a specialized SerivceHost which automatically configures address, binding, contract.
If no endpoint is defined, WebServiceHost automatically creates a default endpoint. WebServiceHost adds WebHttpBehavior and disables the HTTP Help page and the Web Services Description Language (WSDL) GET functionality.
