title: SingleOrDefault() throws an exception on more than one element
body: <p>I'm getting an exception whenever I fetch like this</p>
  
  <pre><code>Feature f = o.Features.SingleOrDefault(e =&gt; e.LinkName == PageLink);
  </code></pre>
  
  <p>because this can return one or more than one element. What is the alternative approach that I can use to solve this issue?</p>
