title: Using a WCF Service with Entity Framework 4 and...DTO?
body: <p>As described above I'm implementing a multi-tier architecture to work with WCF and Entity Framework 4 (with poco). Since I'm already have persistence ignorance with POCO I do need implement DTO or I can use WCF in its pure way?</p>
  
  <p>The main quote is - I do need DTO to pass a lightweight object on the network or I can use my POCO entities.</p>
  
  <p>What you guys recommend?</p>
