Boxing and unboxing the DTE object doesn't allow event subscriptions to work in the VSSDK all the way back to vs2005 and up to vs 2012.

Visual Studio 2012

I believe that boxing and unboxing the DTE object in VS 2005/2008/2010/2012 (I have literally struggled with this since vs 2005 with no solution).

What works:

((DTE)GetService(typeof(DTE))).Events.DebuggerEvents.OnEnterDesignMode += DebuggerEvents_OnEnterDesignMode;

What doesn't work:

var services = new Dictionary<Type,Object>();
services .Add(typeof(DTE), ((DTE)GetService(typeof(DTE))));
services[typeof(DTE)].Events.DebuggerEvents.OnEnterDesignMode += DebuggerEvents_OnEnterDesignMode;

Things considered by other peoples suggestions:

1) caching Events, and DebuggerEvents objects so that they aren't GC'd

DTE events don't work in 80% of cases (consistantly) ie, they work for DTE.Events.DebuggerEvents.OnContextChanged; but not for DTE.Events.DebuggerEvents.OnEnterDesignMode and all of the other events under DTE.Events.DebuggerEvents.*

All events behave the same as how OnContextChanged does where it survives being boxed. This is extremely confusing and unexpected behavior for developers. I went on for a long time coming up with elaborate hacks to try and work around those events not working. I also found that in the documentation for the events it says that you shouldn't use them. That lead to the belief they might have been deprecated which I now don't believe to be the case at all.
