To enable rest feature in WCF service we must do couple of changes,
- Changes in applications main Interface.cs file
- Changes in Configuration file.
Changes that needs to be done in application config file:
Following steps needs to be added in App.config file of the hosting WCF application.
- Search for config tag <service> and under that tag add below <endpoint> tag as highlighted in below screenshot.
address = "rest" // this can be any meaning full name, this name will be refereed in API URL calls later.
binding = "webHttpBinding" // this must be webHttpBinding
contract= "xyz.Iservice" // must be valid contract address
behaviorConfiguration = "jsonBehavior" // this can be any meaning full name, this name will be refereed in this config file later.
2. Search for config tag <behaviors> and under that tag add below <endpointBehaviors> section

- Search for config tag <configuration> and add below section under this tag
4. Search for config tag <system.serviceModel> and add below section under this tag
