title: Why am I not receiving deserialized data in my WebAPI?
body: <p>I've got a simple WebAPI app. In my controller I have:</p>
  
  <pre><code>[HttpPost]
  public ActionResult DoSomeWork(string stringParam, DTOObject dto)
  {
      // Some work gets done in here
  }
  </code></pre>
  
  <p>I've got a console app doing this: </p>
  
  <pre><code>HttpClient client = new HttpClient();
  client.BaseAddress = new Uri(_context);
  client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
  
  var response = client.PostAsJsonAsync("ControllerPath/DoSomeWork", new object[]{someString, dtoObject}).Result;
  </code></pre>
  
  <p>I don't receive any errors. When my breakpoint is hit inside of the Controller, it shows the string coming in as NULL and the DTO coming is a fully populated but with default values (1/1/1900s, nulls, etc). I feel like the controller isn't properly deserializing the object but I'm kind of at a loss of how to fix this. Any thoughts?</p>
