title: Entity Framework 4.0: is it worthy now?
body: <p>I've read a lot complains about Entity Framework in .NET 3.5 SP1, especially about its ineffectively generated SQL. Those complains had prevented me from studying Entity Framework.</p>
  
  <p>Now Entity Framework 4.0 has come out, which provide a lot of promises. I wonder if it's really a good ORM now, or still not yet? Is it worth to learn and use it in my .NET projects, instead of traditional SQL queries? Have you planned to switch to EF 4.0 yet? </p>
  
  <p>Thanks in advance.</p>
