Json crud operation

Hey if you execute GET request, ASP.NET Web API framework will return response in XML, JSON or any other format depending on accept header of request. Chorme and Firefox browser has XML as default value for accept header whereas IE has JSON as default value. So if you execute request through Chrome or Firefox you will get response in XML and if you use IE you will get JSON response.

If you want your Web API should return JSON response as default you will have to configure JSON Media Type Formatter.

Open WebApiConfig.cs file from App_start folder and add below code.

public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Web API routes
config.Formatters.Clear();
config.Formatters.Add(new JsonMediaTypeFormatter());
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
