无法加载文件或程序集“Microsoft.Data.Service”或其依赖项之一。该系统找不到指定的文件

Question

我刚刚切换了我的计算机，我的一个项目不再正常运行并在标题中引发错误。 （您还可以在下面找到完整的错误消息） 它显然是在寻找错误的地方，但此时我不确定要更改什么。请指教。

需要记住的一些事实

• 我没有更改源代码中的任何代码行
• 在由 VSTS 部署的新生产服务器上运行良好
• 我正在使用 IISExpress 来运行它
• 我正在使用 Visual Studio 2015 v14.0.25431.01 更新 3
• 与我上一台计算机的主要区别之一是，这台计算机中有 Visual Studio 2017 RC。 （我认为这不会导致任何事情，但谁知道）

程序和功能

以下应用存在

• WCF 数据服务 5.6.3 工具

Bin目录

以下文件存在

• Microsoft.Data.Edm.dll
• Microsoft.Data.OData.dll
• Microsoft.Data.Services.Client.dll
• Microsoft.Data.Services.dll

DataService.svc （完成）

Answer 1

我不得不重新打开那个项目，发现程序集不在加载的模块中。我检查了为bin\{Configuration} 设置的输出目录，将其更改为bin 解决了这个问题。
