title: Do i need to create automapper createmap both ways?
body: <p>This might be a stupid question! (n00b to AutoMapper and time-short!)</p>
  
  <p>I want to use AutoMapper to map from EF4 entities to ViewModel classes.</p>
  
  <p>1) If I call</p>
  
  <pre><code>CreateMap&lt;ModelClass, ViewModelClass&gt;()
  </code></pre>
  
  <p>then do I also need to call</p>
  
  <pre><code>CreateMap&lt;ViewModelClass, ModelClass&gt;()
  </code></pre>
  
  <p>to perform the reverse?</p>
  
  <p>2) If two classes have the same property names, then do I need a CreateMap statement at all, or is this just for "specific/custom" mappings?</p>
