Nhibernate 使用guid的Sharp架构

我正在使用Sharp Architecture 1.6 VS2010并研究如何使用GUI 但我遇到了一个我无法解决的错误

个人实体

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; }
   }
}

自动映射似乎将未保存的值设置为0。尝试将映射覆盖更改为：

mapping.Id（x=>x.Id）.GeneratedBy.GuidComb（）.Default（Guid.Empty）

看起来自动映射正在将未保存的值设置为0。尝试将映射覆盖更改为：

mapping.Id（x=>x.Id）.GeneratedBy.GuidComb（）.Default（Guid.Empty）

谢谢你的反馈。我在追加.Default（Guid.Empty）时遇到了相同的错误，但这使我尝试了.UnsavedValue（Guid.NewGuid（）），它似乎已经解决了问题。谢谢你，詹姆斯。哦，我的错。谢谢你的关注和更新。我为其他人找到了这个问题的答案。对于Guid PKs，NHibernate应默认使用未保存的Guid.Empty值。是的。不幸的是，Fluent NH在生成映射时显式重写了未保存的值。感谢您的反馈。我在追加.Default（Guid.Empty）时遇到了相同的错误，但这使我尝试了.UnsavedValue（Guid.NewGuid（）），它似乎已经解决了问题。谢谢你，詹姆斯。哦，我的错。谢谢你的关注和更新。我为其他人找到了这个问题的答案。诚实的Fl
