From this desk case:
Customer reported that the exception window in Visual Studio is blank when an exception is thrown, not giving any details on what the exception is: http://screencast.com/t/elfRni8MpEw
The Call Stack and Locals windows should work in the current version even though the exception window itself isn't as detailed as normal exceptions in Desktop apps.

## Regression status: not a regression
## Steps to reproduce
1. Run the attached test case on Android or iOS in Visual Studio.
2. Tap the "Button" button.
When Visual Studio breaks on the unhandled exception, it shows a free-floating exception window that does not include a list of "Actions."
See the attached "Xamarin exception window."
## Desired results
(For example if you follow the steps to reproduce but instead use the Windows Phone project from the test case)
When Visual Studio breaks on the unhandled exception, it shows a different kind of exception "sub-window" that is embedded in the existing Visual Studio window. The bottom of this exception window includes a list of helpful "Actions."
See the attached "Windows Phone exception window."

*** Bug 23566 has been marked as a duplicate of this bug. ***
I have verified and found this has been fixed. It used to be a timing issue (the exception showing before the message can be fetched) that's not present anymore.
