c# - .Net 4.6 网站未正确加载引用程序集

Question

我在 Visual Studio 2013 中有一个 Web 项目，包括几个库项目。

问题是，将引用(即 System.Collection、System.Net)添加到 Web 项目时，正作为“引用程序集”从 C:\Program Files (x86)\Reference Assemblies\Microsoft 添加，当在 IIS 中加载时，它没有正确加载程序集的实现(来自 GAC)。示例错误如下。

[BadImageFormatException: Cannot load a reference assembly for execution.]

从 bin 文件夹中删除引用 dll 可以解决此问题，但我不确定需要更改哪些内容才能正确解决此问题。

Answer 1

我从/Bin文件夹中删除包

System.Collections and System.Collections.Concurrent

并重建项目

它的作品。
