title: IsRowVersion can only be configured for Byte array properties
body: <p>I recently upgraded from EntityFramework 5 to 6 via the NuGet updater. Everything seemed to go well and I built and executed my application. When I tried to retrieve the first entity from the database, I received this error:</p>
  
  <blockquote>
    <p>The property 'UpdatedDate' is not a Byte array. IsRowVersion can only
    be configured for Byte array properties.</p>
  </blockquote>
  
  <p>Here is the piece of code it is referring to:</p>
  
  <pre><code>[Timestamp]
  public virtual DateTime UpdatedDate { get; set; }
  </code></pre>
  
  <p>I tried removing the timestamp attribute, but got the same error regardless. How do I fix this so I can run my application with EF6?</p>
