title: Copy data from one object to another
body: <p>Hey
  I want to copy data from one entity to another.<br>
  I have something like this :</p>
  
  <pre><code>  MyEntity newEntity = new Entity()
    newEntity.Property1 = oldEntity.Property1 ....
  </code></pre>
  
  <p>Is there easier way to do this? I have many properties and I would like to write something like <code>newEntity = oldEntity</code>, but this is impossible because of primary key duplication</p>
