Visual Studio 2015 break on unhandled exceptions not working

Question

Visual studio used to have a specific checkbox to \"Break on Un-handled exception\". In 2015 this has been removed (or moved somewhere I cannot find it). So now my convert

Answer 1

Microsoft have subtly changed the logic in the new exceptions window.

See http://blogs.msdn.com/b/visualstudioalm/archive/2015/02/23/the-new-exception-settings-window-in-visual-studio-2015.aspx

The key part being:

Important Notes

• This new window contains all of the same functionality as the old modal dialog. No capabilities of the debugger have changed only the way you can access them
• The debugger will always break when an exception is unhandled
• The setting to change if the debugger breaks on user-unhandled exceptions has moved under a context menu
• The menu location has moved to Debug -> Windows -> Exception Settings

However, if like me you have a Global Unhandled Exception Handler in your code then the second item on that list is key: For me, no exceptions will therefore be truly unhandled, which seems to be different from VS2013.

To get back the behaviour where VS breaks on unhandled exceptions, I had to tick all of the exception types I wanted to break on and then secondly ensure that the "Additional Options" (you may need to make this column visible*) for "Continue when unhandled in user code" was NOT set. The VS2015 logic does not seem to consider my Global Unhandled Exception Handler to be "handled in user code", so it does break on these; it doesn't break on caught exceptions though. This makes it work like VS2013 did.
