赤い帽子のヤツは助けてくれないし(役立たずめ!)、とりあえずソースコードを探して Visual Studio で開いて実行してみたけど、とくに問題はないみたい。念のため、NuGet を確認してみたら ASP.NET Core 2.0.0 のプレビュー版みたいなやつが入っていたのでアップデート(→ 2.0.3)して再ビルド、発行。





Now that Core 2.0 has been release, App Service will remove support for 2.0 preview runtimes and SDK. This will happen starting in early October 2017.

Action item: make sure that you upgrade all your 2.0 Preview apps to the official 2.0 bits.

See also #27 for a similar announcement relating to prerelease Core 1.x bits.
