title: Web API OData V3 `$inlinecount` fails
body: <p>I am using the out of the box ValuesController in a ASP.NET Web API application</p>
  
  <pre><code> public class ValuesController : ApiController
   {
       // GET api/values
       [Queryable(PageSize = 1)]
       public IQueryable&lt;string&gt; Get()
       {
           return new string[] { "value1", "value2", "value3", "value4", "value5" }.AsQueryable();
       }
   }
  </code></pre>
  
  <p>When I <code>get  http://localhost/api/values?$inlinecount=allpages</code> </p>
  
  <p>This is the response </p>
  
  <pre><code>&lt;ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
  &lt;string&gt;value1&lt;/string&gt;
  &lt;/ArrayOfString&gt;
  </code></pre>
  
  <p>I have uncommented <code>config.EnableQuerySupport();</code></p>
  
  <p>Filtering, sorting work fine. </p>
  
  <p>If I try <code>get  http://localhost/api/values?$inlinecount=XXXXX</code> I get an exception, so it seems the Web API application knows about <code>inlinecount</code></p>
  
  <pre><code>&lt;Message&gt;The query specified in the URI is not valid.&lt;/Message&gt;
  &lt;ExceptionMessage&gt;'xxx' is not a valid value for $inlinecount.&lt;/ExceptionMessage&gt; 
  &lt;ExceptionType&gt;Microsoft.Data.OData.ODataException&lt;/ExceptionType&gt;
  </code></pre>
  
  <p>I definitely have the Microsoft.AspNet.WebApi.OData package - here is the output of the Package Manager Console </p>
  
  <pre><code>PM&gt; Install-Package Microsoft.AspNet.WebApi.OData

  <p>Any suggestions?</p>
