The "Wizard" is mainly responsable for Visual Studio "magic" that goes on behind the scenes.
It also stores the connection in the config file if you want it to.

When you're doing a "manually" connection to the db you do need to specify the conncetion string.

Else the connection is specified in the *.deisgner.cs file along with most of the other magic(datasets and views and...).

I really try to avoid it as much as possible for the simple fact that I like being in control of my code.
Also easier to debug, log... when manually specifiyng the connection.
