恢复 Nuget 包...他从哪里得到用户名？

Question

我在一家新公司工作，第一天我想建立一个解决方案。 但是，这不起作用：

我已经在我的 PC 上本地下载了解决方案。
我已经在我的 PC 上启动了 Visual Studio，并使用我的 hotmail 帐户登录。

当我按下Build时，我收到一个关于我的凭证Dominique.<surname>@<firm>.eu的问题。

确实，我正在为<firm>.eu工作，但我已经删除了我的<firm>.eu Windows 凭据（开始，凭据管理器， Windows 凭据）。 如前所述，我使用我的 hotmail 帐户登录 Visual Studio。

所以我的问题是：为什么 Visual Studio 在恢复 NuGet 包时要求我提供Dominique.<surname>@<firm>.eu凭据？ 有谁知道为什么 Visual Studio 要求 Visual Studio 甚至不应该知道的凭据？

供您参考：当我 go 进入解决方案资源管理器时，我尝试启动“管理 NuGet 解决方案包”，弹出相同的Dominique.<surname>@<firm>.eu凭据问题。

经过更多调查后编辑

显然，这一切都是因为我的公司正在使用 Azure Devops 技术。 在查看相应的帮助页面时，我收到以下消息

“我们有这么多的认证类型和认证方法。”

当我浏览我公司正在使用的参考时，无论是使用我的公司电子邮件还是我的个人电子邮件，我都无法访问（错误消息 TF400813）。

我只想说：我不是坏人：只要给我访问权限！

这是如何运作的？ （请尽可能简单）

另一个编辑

如 Microsoft 网站上所述，我在 NuGet.Config 文件中添加了以下几行：

<packageRestore>
  <!-- The 'enabled' key is True when the "Allow NuGet to download missing packages" checkbox is set.
       Clearing the box sets this to False, disabling command-line, automatic, and MSBuild-integrated restore. -->
  <add key="enabled" value="True" />
</packageRestore>

还有更多信息

正如微软网站上提到的，我可以尝试手动进行还原，但这会失败，因为什么都不应该做：

cd <solution_directory or project directory, the results are equal>
Prompt>msbuild -t:restore

Nothing to do. None of the projects specified contain packages to restore.

Visual Studio 怎么可能不知道他需要恢复一些 NuGet 包？

Answer 1

要强制完全恢复项目的 nuget 包，请执行以下操作：

在您的解决方案（或项目）文件夹的目录中使用nuget restore 。

如果目录中有多个 .sln 或 .csproj 文件，您可以使用以下命令： nuget restore <.sln-or-.csproj-name-without-extension> 。 这可以在任何命令 window 中完成。

感谢@Akshay Gaonkar：

为此，需要将 nuget.exe 包含在您的PATH环境变量中。 请参阅https://docs.microsoft.com/en-us/nuget/consume-packages/install-use-packages-nuget-cli#prerequisites和nuget 不是公认的内部或外部命令，了解如何执行此操作。

这个答案是对导致问题得到解决的评论的总结

Answer 2

凭证似乎来自 nuget package。 您可以检查packages.config中的来源。
