Bob,
Actually this is very much possible & actually quite easy in .NET. As Rinze
suggests normally one cannot "overwrite files that are in use", however .NET
has the ability to create a shadow copy of executables, such that you can
replace the original executable with the new one. To create a shadow copy of
an executable you set the shadow copy option when creating a new AppDomain,
then load your executable in this second app domain. This implies that your
app has a loader "stub" that creates the app domain & executes your actual
program. Using a FileSystemWatch er you could have the AppDomain
automatically restarted when a new version of the app is saved (However I
would simply inform my user to exit & restart the app).

In .NET 2.0 (VS 2005) using ClickOnce is one of the easiest ways to
implement this app loader/updater.
Alternatively (.NET 1.x VS 2003) you can look at the Updater Application
Block:
