Probably a silly question, but...

Suppose I have two apps...

App 1 is a WinForm app that talks 'directly' to SQL Server
App 2 is also a Winform app, but uses a web service to access SQL Server.

Would there be any real difference between a dataset created in app 1, versus app 2 (where a dataset is created by a web service and passed down to the Winform).

Someone told me that there are differences in the way you'd use ADO.NET to work on the dataset locally under app 1 versus app 2...and I don't see how. I realize that any updating of data back in SQL would take on a very different form...but it seems that me that once you have a dataset, it doesn't matter 'how' you got it, you have access to the same ADO.NET properties for the dataset, regardless.

True?

Thanks,
Kevin
