奇怪的 NU1605 引用 NETStandard.Library 1.6.0，而导流点的库实际上引用的是 netstandard 版本 2.0
Bizarre NU1605 referecing NETStandard.Library 1.6.0 when the library of the diversion point is actually referencing netstandard version 2.0
.NET 5 项目在我的工作站上正确构建，但在构建服务器上却崩溃了。此问题在将 .NET Core 3.1 升级到 .NET 5 时立即出现，这与在构建服务器上安装 .NET 5 相吻合。

我怀疑我们通过 Common 得到了错误的引用，除了 CentoScript.Forms 使用更高版本的 Common 应该会破坏引用。无论如何，这是一种错误的解释，因为它一直有效，直到 CentoScript.Forms 的构建目标从 netcoreapp3.1 更改为 net5.0。
我不应该添加对列出的包的引用，我绝对不应该在任何一个请求的版本中添加它们。 net5.0 应该会自动获取更高版本。
是的，我确实想放置两个不同的 .NET 版本标签。多个版本显然在发挥作用。
糟糕，问题是构建服务器上的 nuget 缓存已损坏。
