title: Where is the ExecuteStoreCommand method in Entity Framework 5?
body: <p>I'm using EF5 in VS2012, and I trying to delete all data of some table using <code>ExecuteStoreCommand</code>, 
  something like this:</p>
  
  <pre><code>ctx.ExecuteStoreCommand("TRUNCATE TABLE [" + tableName + "]");
  </code></pre>
  
  <p>but the problem is EF is telling me, method ExecuteStoreCommand not found. I can't understand why?</p>
  
  <p>Can you tell me why?, or give me a performant solution remove all data of the table.</p>
