I've really been a big fan of the Object-Relational mapping (or O/RM) tool LLBLGen Pro. I am very cautious around the average code generator because most box you up inside their black box code. As soon as you need to do something just a little outside the box, you've made your situation worse not better.

The new version has support for nullable types, and even more support for Visual Studio 2005 databinding. Also LLBLGen Pro can generate Compact Framework SQL CE data access layers. If you use it for nothing else, you'll be better off.

I'll try to do a review in the next few weeks.

LLBLGen Pro helps you build solid n-tier .NET applications fast and easy.

LLBLGen Pro is a real time saver for software developers: development time can be decreased by over 50%! LLBLGen Pro generates a complete data-access tier and business façade/support tier for you (in C# or VB.NET), using an existing database schema set. In seconds.

LLBLGen Pro lets software developers focus on the real deal: business logic code, instead of them having to hammer out endless lists of almost the same routines. You design your database schema's with the abstract modelling tools you always use (for example a NIAM/ORM designer like Visio, or an E/R modeller), and LLBLGen Pro takes care of the rest. All you have to do next is modify some of the names LLBLGen Pro has given entities and fields if necessary, and generate code.

LLBLGen Pro comes with a rich, state-of-the-art user interface, which doesn't require an expensive IDE to run. You design your Business Façade tier's functionality inside this designer until you think you're done.
