title: How can I set breakpoint to [DataMember] property
body: <p>I have a 'Serializable' class and it has 'DataMember' properties. 
  How can I set breakpoint when MyProperty is set?
  I try 'Data Breakpoint' in VS, but it is disabled.</p>
  
  <pre><code>[Serializable]
  [DataContract]
  public class MyClass
  {
      [DataMember]
      public bool MyProperty{ get; set; }
  }
  </code></pre>
