これは私のNuget.configがどのように見えるかです

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

無効なフィードがあります。

おそらく、このフィードは無効ですhttps://www.myget.org/F/aspnetlitedev/api/v2/FindPackagesByIdであり、これらのエラーを無視しないと、dnu は失敗します。

オプション dnu restore -? を参照してください。nuget 構成から無効なフィードを削除します。

Visual Studio 2015 でフィードを確認することもできます。
