无法加载文件或程序集 'netstandard，版本 = 2.0.0.0
Could not load file or assembly 'netstandard, Version=2.0.0.0
我在部署 .net Framework 4.5.2 web 后收到以下错误 api。
Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.`
这不会发生在所有端点上，只有一个，我正在使用 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，调试时也不会在本地发生。
我对部署的服务器没有太多控制权，但我知道它是 IIS 8.5 运行 在 64 位 Windows Server Core 2012 R2/1.2.0 （哇）。出现这个问题时机器没有更改配置。
这是完整的堆栈跟踪：

我怎么知道是什么导致了这个问题？
这是另一个程序集的问题。使用 Fuslogvw.exe（程序集绑定日志查看器）查看依赖项。
