无法加载文件或程序集'netstandard，版本= 2.0.0.0 [英] Could not load file or assembly 'netstandard, Version=2.0.0.0

问题描述

部署.net Framework 4.5.2 Web API后，出现以下错误.

I'm getting the following error after deploying a .net framework 4.5.2 web api.

无法加载文件或程序集"netstandard，版本= 2.0.0.0，区域性=中性，PublicKeyToken = cc7b13ffcd2ddd51"或其依赖项之一.系统找不到指定的文件.

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.`

这并不是在所有使用Microsoft.Xrm.Sdk的端点上发生. 事实是，它才刚刚开始发生，没有更新任何软件包.更糟糕的是，即使在调试模式下，即使在使用发布模式进行构建时，也不会在本地发生.

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.

我对要部署的服务器没有太多控制权，但是我知道它是在64位Windows Server Core 2012 R2/1.2.0(aws)上运行的IIS 8.5.开始出现此问题时，计算机没有更改其配置.

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.

我怎么知道是什么原因引起的?

How can I know what might be causing the issue?

推荐答案

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)查看依赖关系.

It was a problem with another assembly. Used Fuslogvw.exe (Assembly Binding Log Viewer) to view the dependencies.
