Restore failed
Error: FindPackagesById: System.Diagnostics.Debug

这是我的Nuget.config的样子

您有一个无效的源。

可能此提要是无效的https://www.myget.org/F/aspnetlitedev/api/v2/FindPackagesById，如果您不忽略这些错误，dnu将失败。

有关选项dnu restore -？，请参见。从nuget配置中删除无效的提要。

您还可以在visual studio 2015中检查提要。在……里面

  Tools-Nuget package manager-Manage nuget packages for solutions

选择一个包源并查看哪个包源生成404

您还可以在浏览器中复制和传递链接。
