How to: Enable and Disable Edit and Continue
You can disable or enable Edit and Continue in the Options dialog box at design time. You cannot change this setting while you are debugging.
Edit and Continue works only in debug builds. For native C++, Edit and Continue requires using the /INCREMENTAL option.
To enable/disable Edit and Continue
Open debugging options page (Tools / Options / Debugging).
Scroll down to Edit and Continue category.
To enable, select the Enable Edit and Continue check box. To disable, clear the check box.
If IntelliTrace is enabled and you collect both IntelliTrace events and call information, Edit and Continue is disabled. For more information, see Configure IntelliTrace.
For more information about these options, see General, Debugging, Options Dialog Box.
