Unit Testing / Integration Testing Web API with HttpClient in Visual Studio 2013

I am having a hard time trying to test my api controller with Visual Studio 2013. My one solution has a Web API Project and a Test project. In my test project, I have a Unit Test with this:

[TestMethod]
public void GetProduct()
{
    HttpConfiguration config = new HttpConfiguration();
    HttpServer _server = new HttpServer(config);

    var client = new HttpClient(_server);

    var request = new HttpRequestMessage
    {
        RequestUri = new Uri("http://localhost:50892/api/product/1"),
        Method = HttpMethod.Get
    };

    request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    using (var response = client.SendAsync(request).Result)
    {
        Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);

        var test = response.Content.ReadAsAsync<CollectionListDTO>().Result;
    }
}

I keep getting a 404. I have tried running my API with one instance of Visual Studio (IIS Express), and trying to debug this Unit Test in another instance. But no luck. I have verified that I can put this url in a browser (when one Visual Studio is debugging) and I see my json response. But I can't figure out how to get it to work with my unit test and HttpClient. I have tried to find examples online but can't seem to find one. Can someone help?
