Breakpoint is used to notify debugger where and when to pause the execution of program. You can delete multiple Visual Studio Breakpoints together. Visual Studio ask for a confirmation dialog to re-ensure if you really want to remove all the breakpoints.
Once you select the “Delete All Breakpoints” option / press Ctrl+Shift+F9 from the debug menu, it will ask for for the confirmation “Do you want to delete all breakpoints?”
If you select “Yes” from the following dialog control, it will clear all the breakpoints, on the other hand selecting “No” would do nothing.
In case you don’t want this confirmation dialog, and you want to delete all the breakpoints without any conformation, you can disable it. Navigate to Tools –> Options –> Debugging –> General, and uncheck the “Ask before deleting all breakpoints” checkbox option.
By default it is enabled.
Hope this helps
