title: Enable Lazy Loading on AfterSaveEntities using Breeze
body: <p>I'm using breeze with EF6 and <code>EFContextProvider</code>.<br> 
  On save changes I'm <strong>using</strong> : </p>
  
  <pre><code>{ TransactionType = TransactionType.TransactionScope };
  </code></pre>
  
  <p>I'd like to use lazy loading for validating my entities easier during the AfterSaveEntities delegate but I can't do that.<br> Trying to set <strong><code>LazyLoadingEnabled = false</code></strong> during the transaction doesn't work.<br> Entities still don't load relations when needed.</p>
  
  <p>Is there any way to do that?</p>
