无法加载文件或程序集＆net;标准版，版本= 2.0.0.0

部署.net framework 4.5.2 web api后，我收到以下错误。

  

无法加载文件或汇编＆＃39; netstandard，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = cc7b13ffcd2ddd51＆＃39;或其中一个依赖项。系统找不到指定的文件。

这并不会发生在所有端点上，只有一个端点，我使用的是Microsoft.Xrm.Sdk。 问题是它刚刚开始发生，没有更新任何包。最糟糕的是，即使在发布模式下构建，在调试时也不会在本地发生。

我无法控制我部署的服务器，但我知道它是在64位Windows Server Core 2012 R2 / 1.2.0（aws）上运行的IIS 8.5。当这个问题开始发生时，机器没有改变它的配置。

这是完整的堆栈跟踪：

我怎么知道可能导致问题的原因？

答案 0 :(得分：1)

这是另一个装配的问题。使用Fuslogvw.exe（程序集绑定日志查看器）查看依赖项。
