We just released a new example: Validation example for both ASP.NET and Windows Forms. This example shows, using SqlServer's Northwind database how LLBLGen Pro v2.5's validation functionality works, using all options available to you: dependency injected validator classes, extended entity classes overriding validation methods and adding validators through overriding the create method. Adapter example uses ASP.NET, SelfServicing example uses WinForms.

Sourcecode is in C#.

Example is written by our support team member David Elizondo!
