I have an MVC 3 web application. I need to step through the controller code.
I set break point in the controller and hit F5. I get this error:
Unable to launch the ASP.NET development server because port ‘xxxx’ is in use.
Any one has the simple steps to help me step through the code?
Visual Studio: 2010
IIS: 7.5
OS: Win 7
I find this can happen if you had been working on an ASP.NET Website (MVC or Forms), and it has been starting the web development server. Then VS crashes and leaves it running. So as @ChrisF recommends, just make sure all the web dev servers are gone, then try again.
Specifically, the process name is either
WebDev.WebServer40.exeor
WebDev.WebServer20.exeThis error is highly unlikely in an IIS hosted scenario.
