LINQ To SQL, Business Layer and LinqDataSource
In playing with LTS I keep coming back to the question "Should the DataContext be exposed to the presentation so that you can use the LinqDataSource?" Does this violate the separation of layers by moving business (domain) logic into the presentation tier?
Dinesh and Scott Guthrie seem to advocate exposure but I could be interpreting them wrong. On the flip side, Rick Strahl posted some stuff that would seem to say no. Note: I do see that he is more concerned with a disconnected state than with the datacontext).
My current thoughts are that this is a six of one/half dozen issue. Seems like I get the business rules (validation, etc) I want separated from the data. Should be maintainable. So for now, I'm going to use it on some legacy applications that are well defined where this would be a definite time saver. We'll see....
