Question

我最近从GitHub（最新版本）获得了Fluent NHibernate，但是当我在调试模式下实例化FluentConfiguration实例时，我被提示输入NHibernate的Configuration.cs文件的位置。我查看了NHibernate的源代码，但一直无法找到它。我使用Visual Studio从源代码构建，并且想知道我是否有可能犯了这样的错误。有人能指出我正确的方向，如何解决这个问题？我的版本是3.2。

更新

我的调试器正式搞砸了 - 我的ISession变量在堆栈跟踪上超时，说明“功能评估被禁用，因为之前的功能评估超时。你必须继续执行以重新启用函数eval。”

我会发布 config 文件，在这里：

最后，Fluent Config

return Fluently.Configure()
                    .Database(
                       MySQLConfiguration.Standard.ConnectionString(_connectionString)
                    )
                    .Mappings(
                        m => m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly())
                    )
                    .BuildSessionFactory();

Answer 1

由于某些原因，调试器似乎无法确切地指出出现问题的确切位置。但根据我的经验，当VS要求您使用Configuration.cs或FluentConfiguration.cs时，这意味着当您调用BuildSessionFactory（）时会出现问题。

我会在那次通话之前设置一个断点，看看你是否在它之前但没有进一步。由于您的标签表明您正在使用Fluent NHibernate，因此逐步使用流畅的api也无法正常工作。您可能希望通过重复分配FluentConfiguration来进行分块，以便能够逐步完成它。

也许您没有正确公开配置。或者您可能正在使用InMemory SQLite数据库。在后一种情况下，您必须将配置存储在变量中，并在打开会话后构建模式。（每个InMemory会话都有自己的内存数据库。）

最后，问题可能是为您的不同项目加载的不同版本。我建议使用NuGet，并在解决方案级别而不是项目级别管理包，以避免类似的问题。

最后，您可能正在使用错误的SQLite程序集。你在运行32位还是64位？

所以，那是在黑暗中拍摄的几张照片。希望他们会帮助你找到你的bug。
