VB.NET barely OO
I know that .NET is OO, but you are hard pushed to find VB.NET apps that are really OO. I think the reason for this is twofold.
Firstly, most VB.NET developers are coming from VB. Most java/c++ developers are writing in c# on .NET. The second reason is that .NET, especially in windows programming, seems still, to be obsessed with the database. You have all these controls that bind to a datasource, directly from the UI. What happened to objects??

VB.NET barely OO - yea right
Any .Net developer that is not programming to an object oriented model, hasn't had sufficient training, and/or experience. Bindingg UI controls directly to the datasource is nice, if all your worried about is a deadline, and the RAD model is accepted, but good .Net developers all have the ability to create scalable N-Tier applications and do.
Don't blame VB.Net, blame the developer using VB.Net.

I Agree...
I agree with the other John Saunders :-)
I'll add that many people who wonder "where's the OO in VB.NET" have recently read a book or article on VB.NET which did not emphasize OO. From this, they conclude that VB.NET does not support OO since, if it did, that would have been in the book. This is a false assumtpion.

On the evidence
Maybe I could have titled my post better. I feel that people are bringing a lot of baggage to VB.NET from VB. I have worked on three previously written VB.NET projects and struggled to find a real class. Programmers where just writing the old style of code and wrapping it in Public Class /End Class clause.

On the evidence
If we are honest with ourselves we'll realize that precious little Java or C# (or even C++) code is actually object-oriented either.
Windows Forms and Web Forms are event-driven procedural models. Sure we _use_ objects, but we don't usually apply OO design to the UI.
Data access code is typically linear. Again, we _use_ objects from ADO.NET, but our actual data access code is most commonly linear, not even procedural.
Most applications have their business logic in or near the UI. At best this logic is typically in some sort of function library. In a class of course, but not designed with OOD...
The fact is that the _vast_ majority of software created in ANY language today is data-centric, event driven and mostly procedural. It is very rare to find an application where the UI, business logic and data access are built following real OO design...
Depressing? Yes. But this is reality...

Depressing? Yeah
I have to agree with Rocky. I keep find duplicated logic because people are not creating objects to model the objects in their system. If different parts of the system are going directly to the same table for different reasons, then we have probably got duplicated code and logic. This can be the source of bugs as the application ages.
Also, it seems that .NET applications is tightly coupled with database stored procedures. I think this is good, as long as the procedures ARE KEPT SIMPLE. I have come across quite a few apps where most of the logic is in the proc. Thats fine, but you can really inherit or share this kind of logic.
I would like to see an emergence of a proper class models. Lets take the business logic back from the UI and the database!
