title: DataContext in CodeBehind?
body: <p>Im working on an ASP.NET app and using LINQ to SQL for the first time and something seems off. Usually on a web project, there is a data access layer, a biz layer and the preso layer....does linq to sql not work this way? I see where other developers have put the DataContext directly into the Preso layer and are calling the DB via linq from there. Is that the correct way to do it? no biz layer?
  Thanks
