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。
Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'System.IO.Pipelines, Version=4.6.26919.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
我在生产中设置了绑定(bind)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framework 4.6.2。有什么想法吗？
使用 FUSLOGVW 的输出进行更新:

最佳答案
使用微软的“程序集绑定(bind)日志查看器”(Fuslogvw.exe)，它会告诉您哪些绑定(bind)请求正在处理以及哪些失败。
https://learn.microsoft.com/en-us/dotnet/framework/tools/fuslogvw-exe-assembly-binding-log-viewer
如果生产环境中未安装fuslogvw.exe，请检查以下内容: using FUSLOGVW.EXE on a machine with no Visual Studio installed
