Cannot attach debugger to w3wp
问题 I'm debugging an ASP.NET application but sometimes cannot find w3wp neither in Visual Studio process list (Menu: Debug -> Attach to Process... ) nor in task manager . I have selected ' Show processes from all users ' and ' Show processes in all sessions ' check boxes. When run the project from localhost , after an unhanded exception happens debugger would attach to w3wp (too late for me to step into code) ! Why I cannot see w3wp sometimes ?
