title: Delete record with composite primary key in OData
body: <p>I have an entity Student. Below is the signature of delete method in ASP.net WebAPI for OData.</p>
  
  <pre><code>public async Task&lt;IHttpActionResult&gt; Delete([FromODataUri] int key)
  </code></pre>
  
  <p>The Student has composite primary key.
  When called from Postman, with</p>
  
  <pre><code>http://localhost:52484/Students/1
  </code></pre>
  
  <p>it doesn't hit the Delete method.
  But it works with other entity with single primary key.</p>
  
  <p>Any suggestions?</p>
