BY LOVE
To enable CORS policy in web api, You need to add this method in your Global.asax file of API project. i.e
        
        protected void Application_BeginRequest()
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
        }

{
    // New code
    config.EnableCors();
}
