私のuwpアプリケーションでAzure Active Directoryを使用してログイン機能を実行しようとしています。これは正常に行われますが、有効期限が切れたときにトークンをリフレッシュすることができず、常に「403 Forbiddenエラーでリフレッシュに失敗しました。リフレッシュトークンが失効または期限切れになりました。私は再度ログインウィンドウを表示しなければなりません。私が認証するために、バージョン2.1.0と次のコードを使用しています:Azure App Services(モバイルアプリケーション)AAD認証トークンのリフレッシュ
private async Task<bool> AuthenticateAsync(bool forceRelogon = false)
{
//string message;
bool success = false;
// Use the PasswordVault to securely store and access credentials.

vault.Add(credential);

}

誰もが私がやっている何と間違って何かを見る、またはAADサービスプロバイダの中何もする必要はできますか?
