.net - Nuget 包存储在哪里？

Question

我阅读了 Microsoft 文档 https://learn.microsoft.com/it-it/nuget/consume-packages/managing-the-global-packages-and-cache-folders :

Whenever you install, update, or restore a package, NuGet manages packages and package information in several folders outside of your project structure

因此，如果我为我的解决方案安装 Bootstrap Package MyFirstSolution，则该包应下载到我的文件夹 global-packages 上，并且对它的引用将添加到我的解决方案中.

如果当我创建 MySecondSolution 并想要添加 Bootstrap VS 时一切正常，则应该只添加对我的项目的引用，但从技术上讲，我必须从包管理器再次下载它，而不仅仅是添加对为 MyFirstSolution 下载的现有包。

同时，每当我通过第三方下载项目时，即使我已经从我制作的其他项目中安装了它，我也必须重新安装所有使用的软件包。

以下是当我安装已安装在另一个项目中(即:在缓存中)的 Newtonsoft.Json 13.0.1 时包管理器的输出:

以下是我安装从未安装在我的计算机上的 FluentAssertions 6.7.0 时包管理器的输出(即:不在缓存中):

如您所见，在第二种情况下，实际上有一些下载(例如:GET https://api.nuget.org/v3-flatcontainer/Fluentassertions/index.json)。

在这两种情况下，都有一个将 Assets 文件写入磁盘。部分。
这就是项目中 NuGet 的实际安装。
如果您手动编辑.csproj添加NuGet，这部分仍然需要执行。
您可以通过解决方案资源管理器中解决方案根项的上下文菜单来完成此操作。
单击恢复 NuGet 包。
