Autofac 3.0不能在Mono上運行

我一直試圖讓Autofac 3.0.1在Mono上工作，但迄今爲止一直不成功。當我嘗試運行引用Autofac 3.0.1在Mono 3.0.5的應用程序，我得到以下異常：Autofac 3.0不能在Mono上運行

有幾件事情要注意。首先，它似乎無法加載System.Core 2.0.5.0。這可能是由於Autofac 3.0.1是一個可移植的類庫嗎？

此問題也導致第二個問題，其中System.Runtime.CompilerServices.ExtensionAttribute中有一個Missing方法.ctor。我發現這個問題的一些信息，看來，這個問題是由於ExtensionAttribute類移動從一個DLL到另一個：http://www.lextm.com/2013/02/how-to-use-nuget-on-mono-part-iv.html

這個問題可以作如下複製（見https://gist.github.com/ErikSchierboom/5047101）：

創建.NET 4.0的控制檯應用程序
加入（例如，通過的NuGet）
參考，Autofac 3.0.1創建ContainerBuilder類
構建康壽的一個實例權證申請
運行在Mono下的控制檯應用程序

有沒有人對如何解決這個問題的想法？

我做了一些更多的測試，並建立了Autofac.Core項目的.NET 4.0類庫的版本。現在，當我構建這個版本並將我的測試項目鏈接到此版本的Autofac.dll（這是一個.NET 4.0庫，而不是一個可移植的類庫）時，Mono下的一切正常。 Mono不正確支持可移植類庫嗎？ – 2013-02-27 14:05:30

經過對主題的進一步深入研究之後，事實證明，問題本身不是可移植類庫。它是便攜式類庫和擴展方法的結合。 Autofac庫定義了擴展方法，這會導致Mono 3.0.5失敗。我在這裏有一個repro這個問題：https://github.com/ErikSchierboom/monoportableclasslibraryextensionmethod – 2013-02-27 14:49:30

你能否把repro放入[Mono Bugzilla]（http://bugzilla.xamarin.com/index.cgi）呢？ – skolima 2013-02-27 23:25:42

我已經創建了此問題的重製： https://github.com/ErikSchierboom/monoportableclasslibraryextensionmethod它包含兩個控制檯應用程序和兩個可移植類庫。一個便攜式類庫將方法定義爲擴展方法，而其他不會。一個控制檯應用程序使用擴展方法版本，而其他控制檯則不使用。要驗證該問題，請在Mono 3.0.5環境中運行這兩個控制檯應用程序。使用擴展方法版本的將崩潰而另一個不會。

單3.0.12具有完全的PCL功能和防止此錯誤的發生：http://www.mono-project.com/Release_Notes_Mono_3.0#New_in_Mono_3.0.12

如果您可以在問題列表中添加錯誤（儘管我不能保證我可以修復此錯誤），那將是非常棒的。 https://code.google.com/p/autofac/issues/list – 2013-03-20 15:40:57

亞歷克斯，我創建了以下錯誤：https://code.google.com/p/autofac/issues/detail?id=417&thanks=417&ts= 1363806624 – 2013-03-20 19:10:51

我不確定要了解，您是否找到解決該問題的解決方法？看起來你連接的項目只是爲了測試問題是否發生。不是嗎？謝謝你的時間。 – ForceMagic 2013-12-10 20:38:26
