Flakey debug behavior in application start, global.asax

Not using Cassini, but IIS7 to run an ASP.NET app.

The debug behavior is flakey. Sometimes it works, sometimes it doesn't. I was able to step into the application start event in global.asax but sometimes I can't.

Sometimes VS2008 opens the published global.asax so I have two instances of global.asax opened in VS, the source and the published.

I reset the AppDomain and IIS and I can't put my finger on why this is happening. Any clues?

To add, while it won't go into application start, I have an OnChangeEventHandler event - it does step into the event handler.

make a change in the web.config, the application pool will recycle and the global.asax code will be loaded, the debugger should still be attached

Visual Studio doesn't connect to w3wp.exe soon enough to handle breakpoints in Application_Start for IIS7-hosted applications. To debug, use the following line to call debugger explicitly, 

System.Diagnostics.Debugger.Launch();

and choose to launch a new instance of Visual Studio.
