、私は私自身の使用のためにIStringLocalizerベースIdentityErrorDescriberを書かれている、誰もが複数の言語のサポートを必要と私は場合にはここでそれを共有したいと思った:)
基本基本的な言語やその他の言語用のリソースファイルを通常の方法で作成することです。 （https://docs.microsoft.com/en-us/aspnet/core/fundamentals/localization）
（あなたは私のクラス名を保持する場合）に位置
：
/リソース/ yournamespace .LocalizedIdentityErrorDesciber.resx
/リソース/ yournamespace .LocalizedIdentityErrorDesciber.fr。resx
など
これらの中で、エラーコード（例：DefaultError、ConcurrencyError）をキーとして使用します。
その後
