问使用ASP.Net + FastCGI-Mono-Server4从Nginx 3.5迁移到4.0后出现错误

EN

我正在使用Nginx + FastCGI-Mono-Server来托管一个小型的asp.net web服务。它在使用FastCGI-Mono-Server2 ( .Net 2.0版本)时运行得很好。我现在需要将asp.net应用程序升级到.net 4.0。这意味着我需要升级到FastCGI-Mono-Server4。我把所有正确的文件都放好了。它起作用了!然而，它总是因为一个神秘的错误而崩溃。

下面是错误：

例外: System.Runtime.FatalException

我在这个项目中确实有一个IHttpAsyncHandler。我想知道这是否与此有关。当我搜索我的错误时，我发现有人(像这样：wcf callback exception after updating to .net 4.0)推荐这个属性：

CallbackBehavior(UseSynchronizationContext=false)

据我所知，这是一个WCF的事情，与我的asp.net网络服务器无关。任何想法都将不胜感激！
