I tried this route, too. It takes too long and you won't really be able
to build in all the features that a framework can offer.

It may depend on if your database is supported by the framework. Most
C# folks are sucked into the MS universe and settle for SQL Server.
Most of the .Net frameworks will support that.

It depends, of course, on your application. If you are looking at
SmartClient applications and not web apps, take a look at DevForce from
IdeaBlade (www.ideablade.com). It has an ORM component. However, it
also has data-binding classes for the UI part of the application. IMO,
they understand the needs and realities of most business application
development. And they solve them with some great tools. For some of the
best documentation around, check out their Concepts guide. As a
customer, I have also found their support to be extremely responsive,
perceptive, and smart.

Conceptually, you can picture DevForce as a usable implementation of
CSLA, which seems to be a highly over-engineered approach. R. Lohtka,
the CSLA author, is a member of their advisory board.
