Getting 404 response from web api

Question

I have webapi and method:

public class ArticlesController : ApiController
{
     //
     // GET: api/values
     public IEnumerable<Article> Get()
     {
         using (CollectionsEntities entities = new CollectionsEntities())
         {
              return entities.Articles.ToList<Article>();
         }
     }
 }

It works fine, and check it in browser:

webapi works

I create a client:

public static class CollectionClient
{
    private static readonly HttpClient client;

    public static Uri ServerBaseUri
    {
        get { return new Uri("http://localhost:10779/api/"); }
    }

    public static Boolean IsDirty { get; private set; }

    static CollectionClient()
    {
        IsDirty = true;
        client = new HttpClient(new DemoHttpMessageHandler());
    }

    // get all articles
    public static async Task<List<Article>> GetAllArticlesAsync()
    {
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        Uri serverUril = new Uri(ServerBaseUri, "Articles");            
        var response = await client.GetAsync(serverUril);

        response.EnsureSuccessStatusCode();

        var articles = await response.Content.ReadAsAsync<List<Article>>();
        IsDirty = false;
        return articles;   
    }
}

The response gets 404 status code: enter image description here

ID_CAP_NETWORKING is checked to make sure it can access internet. Could anybody give me a hand? Thanks in advance!

I only have experience with Android but "localhost" for the emulator is probably different than the "localhost" for your PC. Try using the internal subnet IP instead.

i use 127.0.0.1 instead, still the same, any ideas? – max Dec 21 '13 at 02:45
127.0.0.1 is the same thing as the localhost (a loopback address). You need to use something like 192.168.1.x or whatever the local subnet is. – Dmitry S. Dec 21 '13 at 02:47

In windows phone 7.x, the emulator shared the networking of the Host PC, that means: we could host services on our PC and access them from our code using htt://localhost..

In windows phone 8, the emulator is a virtual machine running under Hyper V, that means: you cannot access services on your PC using htt://localhost..

you must use the correct host name or raw IP address of our host PC in URIs
