如何在System.Web.Compilation.BuildManager中进行调试

Question

如何调试System.Web.Compilation.BuildManager中的事件？在IIS/ASP.net生命周期的哪个阶段调用它？

问题是，我有一些使用PreApplicationStartMethodAttribute的代码，但似乎没有触发。因此，我试图找出最好的方式来附加调试器到它。

这里有一些关于更大问题的更多细节，为什么PreApplicationStartMethodAttribute()在2013年的SharePoint中不起作用？，但是我已经把它分解成一个小问题来尝试并取得一些进展。

到目前为止我只能识别出下面的呼叫堆栈..。

BuildManager.​GetPreStartInitMethodsFromAssemblyCollection() BuildManager.CallPreStartInitMethods ->

我正在处理一个类似的(或者可能是相同的问题)，并且可以给出完整的堆栈跟踪。您可以自己生成它，只需创建一个简单的小MVC应用程序，并在使用PreApplicationStartMethodAttribute调用的方法中抛出一个异常。你会得到：

[ApplicationException: joe was here]
   MvcApplication2.JoeStart.Start() in c:\Users\Joe\Documents\Visual Studio 2012\Projects\MvcApplication2\MvcApplication2\JoeStart.cs:18
