I’m using Sharp Architecture 1.6 VS2010 and investigating using GUIDs
but I’m encountering an error that I’ve been unable to resolve.
Person Entity
using System;
using NHibernate.Validator.Constraints;
using SharpArch.Core.DomainModel;
namespace SharpDemo.Core
{
public class Person : EntityWithTypedId<Guid>
{
[NotNullNotEmpty(Message = "First name must be provided.")]
public virtual string FirstName { get; set; }
[NotNullNotEmpty(Message = "Last name must be provided.")]
public virtual string LastName { get; set; }
}
}
Fluent Mapping
using FluentNHibernate.Automapping;
using FluentNHibernate.Automapping.Alterations;
using SharpDemo.Core;
namespace SharpDemo.Data.NHibernateMaps
{
public class PersonMap : IAutoMappingOverride<Person>
{
public void Override(AutoMapping<Person> mapping)
{
mapping.Schema("dbo");
mapping.Table("People");
mapping.Id(x => x.Id).GeneratedBy.GuidComb();
}
}
}
The solution successfully builds but encounters the below error when
debugging (which I have been unable to resolve). Any assistance is
appreciated.

It looks like the unsaved value is being set to 0 by the automapping. Try changing your mapping override to:
mapping.Id(x => x.Id).GeneratedBy.GuidComb().Default(Guid.Empty);
