C# trick to launch runtime debugger

I have used this trick quite successfully many times to launch a debugger from a running application. It works really well for things that are hard to debug.  Things like DLLs that might be running under a different application, or display tasks that happen periodically and launching the application in the debugger might change the way the application runs and not cause the bug you are looking for.  It works by basically crashing the application with an exception which brings up the dialog to allow you to continue or debug.  You can have visual studio already loaded with the application and choose that instance of VS from the list.  It is a one liner that you add to your code.

So simple. In your C# code, simply add this line.

Debugger.Launch();

You can do this in any language, but I'm using c# at the moment so showing that. This is very handy.
