无法加载文件或程序集“System.IO.Pipelines”

Question

最近，我将控制台应用程序项目从框架4.5.2升级到了4.6.1。一切都在开发环境中正常工作，但是当我将完整的bin文件夹部署到我的生产环境时，我会得到以下错误。

未处理的异常: System.IO.FileLoadException:无法加载文件或程序集'System.IO.Pipelines、Version=4.6.26919.2、Culture=neutral、PublicKeyToken=cc7b13ffcd2ddd51‘或其依赖项之一。所定位的程序集的清单定义与程序集引用不匹配。(HRESULT例外: 0x80131040)

我在生产中设置了绑定重定向，如下所示：

  <dependentAssembly>
    <assemblyIdentity name="System.IO.Pipelines" publicKeyToken="cc7b13ffcd2ddd51" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.6.26919.2" />
  </dependentAssembly>

该文件肯定存在于bin文件夹中，并且我的生产环境安装了框架4.6.2。有什么想法吗？

根据FUSLOGVW的输出更新：

*** Assembly Binder Log Entry  (1/2/2019 @ 11:47:22 AM) ***

The operation failed.

使用微软的“程序集绑定日志查看器”(Fuslogvw.exe)，它将告诉您正在处理哪些绑定请求以及哪些绑定请求失败。

如果生产环境中没有安装fuslogvw.exe，那么请检查以下内容：using FUSLOGVW.EXE on a machine with no Visual Studio installed
