Restore failed
Error: FindPackagesById: System.Diagnostics.Debug

这就是我的 Nuget.config 的样子

<?xml version="1.0" encoding="utf-8"?>
<configuration>

您的 Feed 无效。

此 Feed 可能无效 https://www.myget.org/F/aspnetlitedev/api/v2/FindPackagesById，如果你不忽略这些错误，dnu 将会失败。

查看选项 dnu restore -? 从您的 nuget 配置中删除无效的提要。

您还可以在 Visual Studio 2015 中查看提要。在

  Tools-Nuget package manager-Manage nuget packages for solutions

选择一个包源并查看哪个生成了 404

您也可以在浏览器中复制并粘贴链接。
