title: LINQ - Add property to results
body: <p>Is there a way to add a property to the objects of a Linq query result other than the following?</p>
  
  <pre><code>var query = from x in db.Courses
                  select new
                  {
                      x.OldProperty1,
                      x.OldProperty2,
                      x.OldProperty3,
                      NewProperty = true
                  };
  </code></pre>
  
  <p>I want to do this without listing out all of the current properties of my object. There are many properties, and I don't want to have to update this code whenever I may change my class.</p>
  
  <p>I am still learning with LINQ and I appreciate your suggestions.</p>
