Mono上使用MEFContrib與MVC3時出錯

管理得到Mono & Mod_Mono安裝在我的Centos 5服務器上時，我設法讓服務器激活我的MVC3站點（它在IIS下運行愉快）。Mono上使用MEFContrib與MVC3時出錯

不幸的是，試圖與Apache運行的時候，我得到了一個錯誤：

找不到方法： 'System.Web.Helpers.Chart.ExecuteChartAction'。描述：HTTP 500.錯誤處理請求。

這是我特有的，因爲我根本沒有在Chart代碼中引用Chart類。異常也似乎來自Composition，並且堆棧跟蹤包括對MefContrib的各種引用。

我已經嘗試過在我的bin目錄中有各種不同的.dlls組合。這是一個讓我到這個階段它的當前內容：

MyDll.dll   MefContrib.Web.Mvc.dll System.Web.WebPages.Deployment.dll 
MyDll.pdb   System.Web.Helpers.dll System.Web.WebPages.Deployment.xml 
MyDll2.dll   System.Web.Helpers.xml System.Web.WebPages.dll 
MyDll2.pdb   System.Web.Mvc.dll  System.Web.WebPages.Razor.dll 
HtmlAgilityPack.dll System.Web.Mvc.xml  System.Web.WebPages.Razor.xml 
HtmlAgilityPack.pdb System.Web.Razor.dll System.Web.WebPages.xml 
HtmlAgilityPack.xml System.Web.Razor.xml WebActivator.dll 
MefContrib.dll  System.Web.Routing.dll

凡MYDLL & MyDll2是我所建的項目的DLL包括各種出口&進口服務，爲MEF組成。

我最好的猜測是MefContrib dll中有些東西與Mono不能很好地配合，除此之外，我的項目是一個非常簡單的MVC3應用程序。

完整的堆棧跟蹤：在「/」應用

服務器錯誤此等問題使我回答這個問題： missingmethodexception-w-mono

事實證明，MefContrib設置默認情況下使用DirectoryCatalog，這對Mono來說不起作用（因爲它試圖在沒有任何東西的dll中找到Exports - 在Windows中很好）。

如果您將您的應用程序的Start（）方法中的MvcApplicationRegistry替換爲您自己的自定義應用程序，它只是查看您的dll（並且不掃描整個bin），那麼一切都很開心。

Start（）方法：

var catalog = new AggregateCatalog(
      new AssemblyCatalog(Assembly.GetAssembly(typeof(MyClass))), 
      new ConventionCatalog(new MyMvcApplicationRegistry()));

MvcApplicationRegistry：

public class MyMvcApplicationRegistry : PartRegistry 
     { 
     public MyMvcApplicationRegistry() 
     { 
      Scan(x => x.Assembly(Assembly.GetExecutingAssembly())); 

      Part() 
       .ForTypesAssignableFrom<IController>() 
       .MakeNonShared() 
       .AddMetadata(new PartCreationScopeAttribute(PartCreationScope.Default)) 
       .ExportAs<IController>() 
       .Export() 
       .Imports(x => 
       { 
        x.Import().Members(
         m => new[] { m.GetConstructors().FirstOrDefault(c => c.GetCustomAttributes(typeof(ImportingConstructorAttribute), false).Length > 0) ?? m.GetGreediestConstructor() }); 
        x.Import().Members(
         m => m.GetMembers().Where(mbr => mbr.GetCustomAttributes(typeof(ImportAttribute), false).Length > 0).ToArray()); 
       }); 
     } 
     }
