Multiple action routing error in webapi MVC4 - asp.net-mvc-4

Question

I have write the below configutation code in the webapiconfig.cs file for routing the multiple fintion. In the get methods I am getting the Multiple actions were found that match the request: System.String GetJobDetails(System.String) error.
Webapiconfig.cs code
config.Routes.MapHttpRoute(
name: "RendererAPi",
routeTemplate: "shared/{controller}/{id}",
defaults: new {id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "RendererAPiStatus",
routeTemplate: "shared/{controller}/{id}/status",
defaults: new { action = "getJobStatus", id = RouteParameter.Optional }
);
My controller code :
//post shared/rendererjob
[HttpPost]
public string createRendererJob(HttpRequestMessage request)
{
return "teststring";
}
//put shared/rendererjob/renderGUID
[HttpPut]
public string DoPutRequest([FromUri(Name="id")]string renderGUID)
{
return renderGUID;
}
//get shared/rendererjob/renderGUID
[HttpGet]
public string GetJobDetails([FromUri(Name = "id")]string renderGUID)
{
return renderGUID;
}
//get shared/rendererjob/renderGUID/status
[HttpGet]
public HttpResponseMessage getJobStatus([FromUri(Name = "id")]string jobid)
{
var response = Request.CreateResponse(HttpStatusCode.OK);
string uri = Url.Link("RendererAPiStatus", new { id = jobid });
response.Headers.Location = new Uri(uri);
return response;
}
the 3 URL are working fine, the //get shared/rendererjob/renderGUID[HttpGet] is not working and getting the multiple action error in the browser.
Any one please suggest me on this.
Note : the Route method is not working in the MVC4 VS2012, and unable to instal any patches into my system for this.

The problem is that you have two GET methods with the same signature, so you need to differentiate them somehow. Try adding a Default Action Name to your methods that use the RendererAPi route:
[HttpPost]
[ActionName("Default")]
public string createRendererJob(HttpRequestMessage request)
{
return "teststring";
}
//put shared/rendererjob/renderGUID
[HttpPut]
[ActionName("Default")]
public string DoPutRequest(string id)
{
return renderGUID;
}
//get shared/rendererjob/renderGUID
[HttpGet]
[ActionName("Default")]
public string GetJobDetails(string id)
{
return renderGUID;
}
//get shared/rendererjob/renderGUID/status
[HttpGet]
public HttpResponseMessage getJobStatus(string id)
{
var response = Request.CreateResponse(HttpStatusCode.OK);
string uri = Url.Link("RendererAPiStatus", new { id = id });
response.Headers.Location = new Uri(uri);
return response;
}
Then change the RendererAPi route as follows:
config.Routes.MapHttpRoute(
name: "RendererAPi",
routeTemplate: "shared/{controller}/{id}",
defaults: new {action = "Default", id = RouteParameter.Optional }
);
By the way you don't need to include the [FromUri] attribute for strings.
