我有一个自定义 HttpModule 可以使用内置的 VS 服务器正常工作，但不会从我设置的 IIS 7.5 服务器运行。c# 文件甚至没有被调用。该模块包含在 system.web 中，但是当我在 中添加对该模块的另一个引用时system.webserver，该项目将无法加载，并且出现结构映射 202 异常代码的错误。

我怀疑这个错误的原因与什么时候Structuremap被初始化有关，但我似乎无法弄清楚。我从文件中的ObjectFactory初始化，它工作正常，直到我尝试加载这个模块。Application_Startglobal.asax

任何帮助将不胜感激。

错误是：

更新 - 如果我在我试图调用的模块中初始化对象工厂，站点将再次加载并且处理程序工作。然后在每个加载的页面上调用以下内容时似乎效率低下且不必要。之前，我可以在全局文件的 application_start 中加载一次。

            ObjectFactory.Initialize(x =>
        {
            x.UseDefaultStructureMapConfigFile = true;
        });
