Many of the customers have reported that they see NotSupportedException/NotImplementedException being thrown when debugging a Codeduitest.
The NotSupportedException/NotImplementedException here in innocuous and is expected. The reason why we see debugger breaking at this exception is because the debugger option has of “Breaking at any CLR exceptions is switched on”. So any time an exception is thrown the VS Debugger will break at that point even if it is handled else where.
To disable this follow the below steps.
1) Click Debug->Exception menu item.
2) It will open an exception dialog. Uncheck Common language runtime exception check box (under thrown column header). See below
Now you are good to go with debugging your codeduitest.
