I know how to run and debug an add-in using the right click add-ins>Debug add-in. I use the Attach to Process in VS to attach to Explorer. The add-in is working fine when testing in Debug but when I add it as a standard add-in there is an error for one of the events. I tried to attach to the explorer process and set a breakpoint but I get the "This breakpoint will not currently be hit" message. Does anyone know how to debug a standard running add-in?
