我可以用 net45 安全地替换 nuget 包上的所有 net46 依赖项吗？

Question

我的项目开始时是 .net 4.6，但后来我想添加对 Interop.CERTENROLLLib.Unofficial 的引用，但我不能，所以我将项目更改为 .net 4.5，然后我可以添加该引用。

但所有其他参考文献都在 46 中

在 VS 中我收到很多警告，我该怎么办？我应该手动降级还是？

Answer 1

当一个人发现自己处于这种情况时的正确解决方案......

1. 将存在运行时目标冲突的项目设置为您想要的运行时，即 NET45 或 NET46。
2. 然后使用 NuGet 包管理 CLI 调用重新安装包。

CLI:> Update-Package -proj MyProject -reinstall

它不仅修复了packages.config，还修复了.CSPROJ 依赖项和web.config 程序集重定向。

Answer 2

最后我创建了从 scatch 到 .net 4.5 的项目并手动添加了引用，然后所有警告都消失了。
