Devops MSBuild 错误无法找到 NuGet 包

如何解决Devops MSBuild 错误无法找到 NuGet 包

我创建了一个 DevOps 管道来构建 asp.net 网站。我可以在我的计算机上构建站点，但是当我使用 Pipelines 时，它会出错：

Error CS0246: The type or namespace name 'Azure' Could not be found (are you missing a using directive or an assembly reference?

我从 NuGet 安装了三个 Azure 包，根据 NuGet 还原任务，它正在安装它们（和其他包）而没有错误

因此，即使 NuGet 任务成功完成并恢复了 Azure 包，它也无法找到它们（无法找到 EPPlus，然后它会给出有关 Azure 缺少引用的错误）

解决方法

nuget.exe 版本4.4.1太旧，在恢复过程中难免会出现一些不清楚的问题。

我建议您可以尝试使用最新的 nuget 版本 5.9.1 来恢复 nuget 包。另外，不要忘记不要使用本地 nuget 缓存。

像这样：

5.x 表示最新的 nuget.exe 版本。

并选中此选项。
