Then select the check box for a specific exception within that category, such as System.AccessViolationException. You can also select an entire category of exceptions.
Note Adding conditions to an exception is new in Visual Studio 2017. To add conditional exceptions:. Choose the Edit conditions button in the Exception Settings window, or right-click the exception and choose Edit Conditions. To add extra required conditions to the exception, select Add Condition for each new condition. Additional condition lines appear.

If you need to delete a condition, choose the X at the end of the condition line. See also Feedback.
