我有一个解决方案，其中很少有 nuget 包。

这些包引用了不同的网络框架。例如。很少有人针对 net451，有些针对 net452，有些针对 net461。

我的项目有 net461 框架。所以我使用该命令Update-Package --reinstall重新安装了针对 net461 框架的软件包。

那成功了，但是我不确定为什么添加了比我已经拥有的更多的软件包？

但我不确定为什么添加了比我已经拥有的更多的包？

这是 NuGet 默认行为。当我们将 nuget 包安装到项目中时，nuget 也会将其依赖项添加到项目中。

添加更多包的原因是它们针对不同框架时的依赖关系不同。当您定位.net461. 因此，添加了比您已经拥有的更多的包。

例如，您可以检查包的依赖关系Microsoft.Extensions.DependencyInjection，System.Net.Http并且System.Runtime.InteropServices：

Update-Package -reinstall显然，当您使用命令重新安装针对 net461 框架的包时，这些包将向项目添加一些新的依赖项。

希望这可以帮助。
