Stephane,

You don't want to mess with the generated code. I recommend using an Interface and then create a sub-class from your typed DataSet. Something like this:

public interface IMyDataSet
{
  void MyDataSetMethod();
}
public class Ar_CustMaster_DataSet : Ar_CustMaster, IMyDataSet
{
  public void MyDataSetMethod()
  {
    // whatever code
  }
}
