Question

私は.Net Coreのアプリケーションで正常に動作しています。しかし、今日、私はoutputに警告が含まれていることがわかりました。

ラインThere was a conflict between "Microsoft.Extensions.DependencyModel...：detailedにログレベルを設定した後、私は次のことを発見しました。 .Net standard 1.1とSystem.Reflection.EmitパッケージをNuGetから使用しているだけなので、この警告を回避するには暑いとは知らないので、他には何も参照しません。もちろん

、私はこの警告を無視しますが、詳細なログによると、いくつかの解決策

Answer 1

を探していることができ、私たちは「によって必要とされるMicrosoft.Extensions.DependencyModel、バージョン= 1.0.1.0を、その依存関係を発見しました

したがって、プロジェクトをコンパイルすると、バージョン1.0.0.0のこの依存関係が選択され、その矛盾が発生します。この警告の問題を解決するために、バージョン1.0.1.0を指定して依存関係「Microsoft.Extensions.DependencyModel」を追加するNuGet
