title: Cannot convert lambda expression to type “string” because it is not a delegate type?
body: <pre><code>       var viewModel = new CoachIndexData();
  
          viewModel.Coaches = db.Coaches
              .Include(i =&gt; i.Courses.Select(c =&gt; c.Department))
              .OrderBy(i =&gt; i.LastName);
  </code></pre>
  
  <p>I Can not Understand how to do it. I am new in ASP.NET MVC</p>
