Unable to attach to application 'WebDev.WebServer.EXE'
Unable to attach to application 'WebDev.WebServer.EXE' is one of the worst errors that I've encountered recently.
There are three work arounds for this error:
1. Reboot your machine.
2. Add paths to Norton Anti-Virus.
3. If you have a copy of two web projects in the same solution change the port and the file name.
Our solution contained a copy of two web projects. Both web projects were configured to use a specific port. We have a test harness that posts XML to a web page that required a specific port. Somewhere along the line, Visual Studio was confused; when one project was run, it actually tried to debug the old project.
Hopefully this information helps someone.
