One last question, I hope. If I want to execute the verifiers for an entity and its child entities how would I set that up.

Hi - sorry, I don't quite understand what behavior you're looking for.  Do you want an exception thrown?  If so, you should set VerifierOptions.ErrorNotificationMode to VerifierErrorNotificationMode.ThrowException or VerifierErrorNotificationMode.NotifyAndThrowException.

MinLenghtStringVerifier min = new MinLenghtStringVerifier();
min.VerifierOptions.ShouldExitOnBeforeSetError = true;

and

min.VerifierOptions.ErrorNotificationMode = VerifierErrorNotificationMode.Notify;

verifiers.Add(new MinLenghtStringVerifier());

private class MinLenghtStringVerifier : StringLengthVerifier

    {

        public MinLenghtStringVerifier()

            : base(typeof(Employee), Employee.PropertyMetadata.FirstName.Name, true, 1, 30)

        {

            this.VerifierArgs.ErrorMessageInfo.ErrorMessage = "First Name can not be blank!";

        }

[DataAnnot.MetadataType(typeof(EmployeeMetaData))]

  public partial class Employee {

….}

public class EmployeeMetaData

{

      [IdeaBlade.Validation.StringLengthVerifier(MinValue=1, ErrorMessage="First Name is required.", IncludeMaxEndpoint=true)]

      public static string FirstName;

}

public class VerifierProvider : IVerifierProvider {

      #region IVerifierProvider Members

      public IEnumerable<Verifier> GetVerifiers(object verifierProviderContext) {

        List<Verifier> verifiers = new List<Verifier>();

        //verifiers.Add(GetHireDateRangeVerifier());

        //verifiers.Add(new BirthDateRangeVerifier());

        //verifiers.Add(GetBornBeforeHiredVerifier());

        //verifiers.Add(GetPhoneNumberVerifier(Employee.PropertyMetadata.HomePhone));

        verifiers.Add(NameRequiredVerifier());

        return verifiers;

      }

      #endregion

    }

    private static Verifier NameRequiredVerifier()

    {

        Verifier v  = new DelegateVerifier<Employee>("First Name is required", MinLengthCondition);

        v.AddTrigger(new TriggerItem(typeof(Employee), Employee.PropertyMetadata.FirstName.Name));

        v.VerifierOptions.ExecutionModes = VerifierExecutionModes.OnBeforeSetTriggers;

        return v;

    }

    private static VerifierResult MinLengthCondition(Employee address, TriggerContext triggerContext, VerifierContext verifierContext)

    {

        return new VerifierResult(triggerContext.ProposedValue.ToString().Length > 0);

    }…..}

When I run VerifierEngine.Execute(Entity x) the verifier collection returned doesn't include my custom verifiers. I can step through and watch them run but the are not in the collection returned. It only includes the foreign key constraint verifiers. Why is that? I have tried using the generic EntityModel.Entity and the specific Contact when running execute.
