Did you still want the question answered or did you post this in some other thread?

Yes I wish to have an answer, its a vb question but I accidentanly post it in here C#, but I cannot delete, so I posted it in VB.net section, anyway here's the question just in case:

I've watch video tutorials on vb 2008 N-tier applications and they teach the new method of separating the tableadapter and dataset while having wcf and then those contract stuffs, but what if I'm not hosting the tableadapter on the server, I just want my client app to connect to the database directly using its datalayer dlls. Im not needing any webservices or any sort of communications. Could I just go on without WCF? Its just a simple windows application that connects to a database that has stored procs and then edit-save. I'm planning on using Linq to sql. Any suggestion regarding a much better approach is appreciated. Thanks
