Craig,

I use Nettiers, www.nettiers.com which creates through code generation and based on ORM and 3 tiers design, typed datasets.
They offer a lot of flexibility, are fast and I'm very pleased with them.

Some code example :
Employee employee=new Employee();
employee.Name="John";
EmployeeProvider.Save(employee);

or
Employee employee=EmployeeProvider.GetByEmployeeID(12); //primary key
employee.Salary=4000;
EmployeeProvider.Save(employee);

or
EmployeeCollection employees=EmployeeProvider.GetByDepartmentID(10); //foreign key


All I need to code, the rest is generated behind the scenes.
