Unity：无法解析类型名称或别名 x。请检查您的配置文件并验证此类型名称

Question

错误代码：

The type name or alias UnitOfWorkFactory could not be resolved. 
Please check your configuration file and verify this type name.

我正在抓取 google 结果/尝试调试 2 天，但我还没有找到任何解决方案。

提到 "ApplicationService" 正在解决。

我多次验证程序集和命名空间的名称
我已经在配置文件中尝试过这个概念：和其他概念。
我验证了与数据库的连接。
我在 VS 中尝试调试模式但没有成功。
可能还有一些我现在不记得的东西。

下面是我的代码，希望足够了。如果还有其他 file/info 被我遗漏了，我深表歉意，我会立即编辑 post。

IApplicationService.cs

我该如何解决这个问题？英语不是我的母语；请原谅输入错误。

Answer 1

改用 <alias> 元素。这是 Unity 配置架构的 link

<unity>
   <alias alias="IUnitOfWorkFactory" type="Abc.Project.Domain.Repository.UnitOfWork.IUnitOfWorkFactory, Abc.Project.Domain.Repository" />

   <alias alias="UnitOfWorkFactory" type="Abc.Project.DataAccess.NHibernate.UnitOfWork.UnitOfWorkFactory, Abc.Project.DataAccess.NHibernate"/>

</unity>

<typeAlias>-Element 已过时并且不再支持取决于您的 Unity 版本。

Answer 2

未引用 UnitOfWorkFactory 的程序集

Unity：无法解析类型名称或别名 x。请检查您的配置文件并验证此类型名称

Unity: The type name or alias x could not be resolved. Please check your configuration file and verify this type name
