title: Maximum number of entity you have ever used for entityframework in your projects?
body: <p>We have a 500+ tables in our sql server database. </p>
  
  <p>We want to update our project to new generation techniques. We want to use entity framework as ORM for DAL. We started to develop small modul of project with  c# -> asp.net -> mvc3 ----soa-- wcf -> (Repository Pattern) EF. </p>
  
  <p>Almost we used 50+ entity in entity framework in the initial project. The performance seems good. But we are worried about how performance will be, if entity number will 500. </p>
  
  <p>What do you advice to us?</p>
