2) Manually attach an ASP.NET workflow that is already running through Debug..Attach to Process?
3) You set debug = "true" in the <compilation> web.config element, that is: <compilation defaultLanguage = "C #" debug = "true">
4) If this is a client-side jscript breakpoint, did you enable script debugging in Tools .. Internet options ... Added ..... check the "Disable script Debugging" checkbox?
