Question

what happens if you put a breakpoint on a click activity and start the workflow in debug mode

Answer 1

When you use Windows Workflow Designer, you can set breakpoints on your graphical workflows as you would do in Visual Basic or C# code.

As expected, workflow execution stops at each breakpoint that you set.

If you put a Breakpoint on a Click activity and start the workflow in Debug mode then, the workflow will be paused until you click the Continue button.
