c# - 找不到程序集“mscorlib，版本 = 2.0.5.0

Question

我已将 System.Net.Http 更新到 4.3.3，从那时起我就收到此错误。一个问题是为什么它仍在获取 System.Net.Http 2.2.9 文件，而它不存在于 packages 文件夹中。 System.Net.Http.Extensions 不在我的引用列表中。我在哪里可以获得最新的dll？感谢任何帮助。

这是详细模式下的构建日志

Answer 1

您可以检查 nuget 包是否退出使用包管理器控制台重新安装包:

 Update-Package -reinstall 

您需要将所有 dll 从 debug 文件夹 复制到 release 文件夹。

还有一件事:确保您的项目文件不是只读的。如果它是只读的，则通过右键单击项目文件夹并选择属性来删除只读属性。在属性屏幕中删除只读复选框。
