本文介绍了无法加载文件或程序集 'netstandard, Version=2.0.0.0的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在部署 .net framework 4.5.2 web api 后收到以下错误.
无法加载文件或程序集netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51"或其依赖项之一.系统找不到指定的文件.`
这不会在所有端点上发生，只有一个，我使用 Microsoft.Xrm.Sdk.问题是它刚刚开始发生，没有更新任何软件包.最糟糕的是，它不会在本地发生，在调试时，即使使用发布模式构建也是如此.
我对部署的服务器没有太多控制权，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.出现此问题时，机器尚未更改其配置.

解决方案
这是另一个程序集的问题.使用 Fuslogvw.exe (Assembly Binding Log Viewer) 查看依赖.
I'm getting the following error after deploying a .net framework 4.5.2 web api.
This doesn't happen on all the endpoints, just one, where I'm using Microsoft.Xrm.Sdk.The thing is that it just started to happen, didn't update any packages. And worst, it doesn't happen locally, when debugging, even if building with release mode.
I don't have much controll over the server where I'm deploying, but I know it's IIS 8.5 running on a 64bit Windows Server Core 2012 R2/1.2.0 (aws). The machine hasn't change its configuration when this problem started to happen.

How can I know what might be causing the issue?
解决方案
It was a problem with another assembly. Used Fuslogvw.exe (Assembly Binding Log Viewer) to view the dependencies.
