我确实选择了解决方案来将包恢复到我的项目解决方案 .sln 文件.... 内置代理队列 Hosted VS2017....

我做错了什么？：/

【问题讨论】：

标签： xamarin.forms xamarin.android azure-devops azure-pipelines

【解决方案1】：

这是我的错，在我的项目中有 nuget 包和引用的 MvvmLight（不是网络标准）包。

然后在我的代码中我直接通过 dll 引用（通过 Resharper 的帮助，我认为是由 nuget 包引用的）

我删除了所有引用并为 .net 标准包安装了 MvvmLight，它现在可以工作了。
