Autofac 3.0.1 を Mono で動作させようとしてきましたが、今のところ成功していません。Mono 3.0.5 で Autofac 3.0.1 を参照するアプリケーションを実行しようとすると、次の例外が発生します。

注意すべき点がいくつかあります。まず、System.Core 2.0.5.0 をロードできなかったようです。これは、Autofac 3.0.1 が移植可能なクラス ライブラリであるためでしょうか?
この問題は、System.Runtime.CompilerServices.ExtensionAttribute に Missing method .ctor がある 2 番目の問題にもつながります。この問題に関する情報をいくつか見つけました。この問題は、ExtensionAttribute クラスが DLL から別の DLL に移動したことが原因のようです: http://www.lextm.com/2013/02/how-to-use-nuget -on-mono-part-iv.html
この問題は次のように再現できます ( https://gist.github.com/ErikSchierboom/5047101を参照)。
- .NET 4.0 コンソール アプリケーションを作成する
- Autofac 3.0.1 への参照を追加します (NuGet 経由など)。
ContainerBuilder
クラスのインスタンスを作成する- コンソール アプリケーションをビルドする
- Mono でコンソール アプリケーションを実行する
この問題を解決する方法を知っている人はいますか?
