NHibernate,Fluent NHibernate和Iesi.Collection问题.接下来你会尝试什么？

Question

我对NHibernate非常陌生,所以如果我在这里遗漏了一些微不足道的话我会道歉.我目前正在编写一本名为"NHibernate 3初学者指南"的书,来自packtpub.我大多数都遵循书中的指示.当我说大多数情况下我使用MySQL而不是MSSQL而已经分歧并且一直在使用NuGet而不是手动下载二进制文件.

我现在在第2章,这是第一个真正的编码章节.在本章中,我将构建一个简单的WPF应用程序,通过单击按钮来构建我的数据库模式.我已经为本章中指定的类Product和Category类构建了一些POCO .通过NuGet,我添加了以下参考:

1. MySQL.Data
2. NHibernate(作为依赖自动解析,Iesi.Collections)
3. 流利的NHibernate

当我单击按钮来构建我的数据库时,执行以下代码块:

private const string connString = "string omitted for brevity";

private void btnCreateDatabase_Click(object sender, RoutedEventArgs e)
    {
        Fluently.Configure().Database(MySQLConfiguration.Standard.ConnectionString(connString))
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<ProductMap>())
            .ExposeConfiguration(CreateSchema)
            .BuildConfiguration();
    }

单击按钮后,我收到以下异常(FileLoadException):

外部异常消息: Could not load file or assembly 'Iesi.Collections, Version=4.0.0.0, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

内部例外消息: Could not load file or assembly 'Iesi.Collections, Version=1.0.1.0, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

如果有帮助,这是"Fusion Log":

我尝试了以下内容,现在有点亏本:

1. 试图通过NuGet升级Iesi.Collections但是没有说NHibernate没有兼容的版本.
2. 下载NHibernate和FluentNhibernate的二进制文件并手动引用它们.
3. 从书中提取源样本并复制样本中的DLL.这给了我一个不同的错误,我还没有进行足够的研究来提问.

我有两个问题:

1. 首先,为什么当发布的版本指向1时,NuGet包会尝试寻找版本4.*dll？*？
2. 我应该尝试哪些其他方法来获取所有来源并在本地构建？我有点失落,并且会喜欢其他一些输入.

提前致谢!

神圣的蠢货让我疯狂.我发现app.config在某个时刻创建了一个,大概就是因为我在弄乱某些东西.在app.config我发现以下内容:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Iesi.Collections" publicKeyToken="aa95f207798dfdb4" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

注释掉Runtime元素,重建和运行允许上面的按钮正常运行.我不知道我做了什么导致这个产生,但我很高兴我找到了它.非常感谢您为此提供的帮助和感谢!

Iesi.Collections 4.0是一个针对.Net 4.0的大量修改版本,用于未来的NHibernate 4.0.

不幸的是,NHibernate版本(包括3.3.1)的Nuget包不指定Iesi依赖项的上限.随着NHibernate 3.3.2的改变,明确禁止Iesi版本4或更高版本.因此,如果您通过NuGet更新到NH 3.3.2,我希望它将Iesi依赖关系解析为3.x版本.
