When you are working with multiple breakpoints set over multiple code files of a large project or solution, it is sometimes difficult to identify and manage them properly. Visual Studio provides a better way to organize them.
As shown in the following screenshot, right click on a specific breakpoint and click on Edit Labels.... Alternatively, you can press Alt + F9 + L to open the breakpoint labels dialog:
This will open the Edit breakpoint labels dialog window, as shown in the following screenshot:
If you have already defined any labels within the same solution, this will list all of them here. You can add a new label to your selected breakpoint or associate it with other breakpoint labels listed in this screen.
Note that you can add multiple labels to a single breakpoint from the Edit breakpoint labels dialog box.
