MySQLデータベースに接続しようとすると例外がスローされる

Question

.NET/Mono用のMySQLドライバ（v6.9.8）を使用する簡単なアプリケーション（.NET 4.5.2）があります。 .NET（Windows）では完全に動作しますが、Connectメソッドを呼び出すとすぐにUbuntu（Mono v4.2.1）で例外がスローされます。

Answer 1

ファイルまたはアセンブリ「System.Managementをロードできませんでした、バージョン= 4.0.0.0

System.ManagementはWindowsでのみ動作しますライブラリです。 MySQLコネクタドライバが突然このライブラリに依存し始めた場合、これはかなり悪いことです。 IIRCでは、Mysql .NETコネクタは常にMonoと連携していましたので、この問題を回帰として報告する必要があります。
