The aim here is to incorporate StackOverflow popular answers into Visual Studio's Exception Assistant.
I have trawled the web without luck, the only information I could find about customizing the Exception Assistant is this link below that shows how to add links to the "Troubleshooting Tip" area:
My question is it possible to tap into other areas of the Exception Assistant such as: Actions, View Details?
I also found that adding links to Troubleshooting Tip area is limited: http://social.msdn.microsoft.com/Forums/en/vsx/thread/3b045e98-081c-4540-b27b-3121245e53ee,
I have posted the idea on Microsoft's Visual Studio suggestion site, vote for it if you like the idea: http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2847295-exception-assistant-exstensibility-to-tap-into-t
UPDATE (May 2015):
Microsoft is doing something similar with Developer Assistant, just need to tap into the error assistant with StackOverflow in the same way: https://visualstudiogallery.msdn.microsoft.com/a1166718-a2d9-4a48-a5fd-504ff4ad1b65
