无法加载文件或程序集'System.IO.Pipelines'

Question

我最近将我的控制台应用程序项目从框架 4.5.2 升级到 4.6.1。在开发环境中一切正常，但是当我将完整的 bin 文件夹部署到生产环境时，出现以下错误。

未处理的异常：System.IO.FileLoadException：无法加载文件或程序集"System.IO.Pipelines，版本=4.6.26919.2，区域性=中性，公钥令牌=cc7b13ffcd2ddd51"或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。（HRESULT的例外：0x80131040）

我已经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，我的生产环境安装了框架 4.6.2。有什么想法吗？

使用 FUSLOGVW 的输出进行更新：

使用Microsoft的"程序集绑定日志查看器"（Fuslogvw.exe），它会告诉您正在处理哪些绑定请求，哪些请求失败。

如果生产环境中未安装 fuslogvw.exe，请检查以下内容：在未安装 Visual Studio 的计算机上使用 FUSLOGVW.EXE
