WebApi cors for runtime 4.0

CORS is natively supported in Web API 2 only. However, you can write your own extensions. Take a look at this tutorial by Carlos Figueira. The tutorial not only applies to the RC version but also to final version 1.

You need to check EF version before inastalling above package if it is EF version 4.5 and above then it works otherwise it rollbacks below EF version 4.5

And ** Access-Control-Allow-Origin ** problem is solved no need to do extra work

and you can do it in VS 2013 web express

using System.Web.Http.Cors; namespace WebApplication10 { public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API configuration and services var cors = new EnableCorsAttribute("*", "*", "*"); config.EnableCors(cors); // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } } } 

Hope this will help Thank you

This is WebApiConfig.cs file

var cors = new EnableCorsAttribute("*", "*", "*"); config.EnableCors(cors); 

and using System.Web.Http.Cors;

these are the changes you need to do. For Api Controller

public class ValuesController : ApiController { // GET api/<controller> [HttpGet] public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; } 

just add [HttpGet] attribute and all is set.

For IIS 6 servers:

To CORS-enable Microsoft IIS6, perform the following steps:

• Open Internet Information Service (IIS) Manager
• Right click the site you want to enable CORS for and go to Properties
• Change to the HTTP Headers tab In the Custom HTTP headers section, click Add
• Enter Access-Control-Allow-Origin as the header name
• Enter * as the header value
• Click Ok twice

For IIS7

Merge this into the web.config file at the root of your application / site:

 <?xml version="1.0" encoding="utf-8"?> <configuration> <system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> </httpProtocol> </system.webServer> </configuration>
