title: removing duplicates in a list with linq
body: <p>Suppose you have a list of MyObject like this:</p>
  
  <pre><code>public class MyObject
  {
    public int ObjectID {get;set;}
    public string Prop1 {get;set;}
  }
  </code></pre>
  
  <p>How do you remove duplicates from a list where there could be multiple instance of objects with the same ObjectID.</p>
  
  <p>Thanks.</p>
