title: Initial Value of an Enum
body: <p>I have a class with a property which is an enum</p>
  
  <p>The enum is</p>
  
  <pre><code>/// &lt;summary&gt;
  /// All available delivery actions
  /// &lt;/summary&gt;
  public enum EnumDeliveryAction
    {
      /// &lt;summary&gt;
      /// Tasks with email delivery action will be emailed
      /// &lt;/summary&gt;
      Email,
  
      /// &lt;summary&gt;
      /// Tasks with SharePoint delivery action 
     /// &lt;/summary&gt;
     SharePoint
    }
  </code></pre>
  
  <p>When I create an instance of this class, NOWHERE in the code, do I specify the value of the enum field, but it seems to default to the first item in the enumlist, and not a null value, is this how enums work? How is it possible to ensure that the enum gets some kind of null value if it is not set, I don't want it defaulting to the first value in the enum.</p>
