Answer 1

包xxx与netcoreapp3.0不兼容

如果解决方案中的所有项目都以.net core为目标，请使用这样的Use .net core task+dotnet restore：

​

​

如果您的解决方案包含以.net core+.net framework为目标的项目，那么您可以像这样使用Use nuget+nuget restore：

​

​

您应该指定要使用的nuget.exe版本。Nuget 5.3.1是在我的管道中运行良好的版本。此外，还可以选择启用Always download the latest matching version框。参见类似的问题这里。

当前的.NET SDK不支持针对.NET Core3.0。要么以.NET Core2.1或更低版本为目标，要么使用支持.NET Core3.0的.NET SDK版本。

它指示您应该使用代理与VS2019+corresponding .net core sdk一起运行还原。如果使用的是microsoft托管代理，则在排队构建管道时应使用window 2019代理。如果使用VS2017-Window2016代理，您将遇到这个问题。

此外，您应该确保安装了相同或更高版本的.net核心sdk。(链接这里)。如果使用私有代理，可以在排队之前手动安装相应的sdk；如果使用托管代理，则可以使用Use .net core 3.x task。
