无法解决，因为它间接依赖程序集- Azure DevOps构建管道

Question

我有两个项目。项目1和项目2.项目1是指csproj文件中的项目2。我最近将项目2升级为更高版本的.NET。当我对项目1做同样的操作并运行我的CI管道时，我收到了很多错误，主要如下所示。当我分别为Proj 2运行CI管道时，它正在成功地构建。

我检查了所有可能的地方，看看是否有任何旧的参考资料，但我无法找到问题到底在哪里。谢谢你的帮助。

项目的依赖项与项目现在的.NET版本不匹配。我也遇到了同样的问题，并使用前面提到的这里方法重新安装了包。简而言之:在包管理器控制台中运行update-package <package name> -reinstall

在您更改.NET版本的项目中安装的所有包都要这样做。
