Here’s how you can add a button to the Debug toolbar in VS:

Attach to a process or run a project so that your solution is in “Running” mode

I’ll attach to devenv.exe (and make sure that I have selected “Managed (v4.5, v4.0) code” as the code type that I want to attach to, otherwise some of the debugging commands won’t apply).

Find the Debug Toolbar (depending on your VS settings, this toolbar might not show up, that’s ok, you can add any button to any toolbar)

Hit the drop down arrow at the right side of the toolbar and select “Add or Remove Buttons” >> “Customize”

On the Customize window press “Add Command…”

Select the Category and Command that you are looking for then hit “OK”

Hit the “Close” button on the Customize window

The new button will now be in the toolbar
