While I was debugging the program in Visual Studio 2010, a dialog box appeared and asked if I wanted to open the firewall due to a remote debugging request.
Does this mean that the person initiated this request?
Plain:
This means that you are trying to debug a method that belongs to an assembly on another computer (another computer / server / device / ...)
