Open a command line and go to %windir%\Microsoft.NET\Framework\v2.0.50727 (usually C:\Windows\Microsoft.NET\Framework\v2.0.50727) Run the following command, where <WWWROOT> is your path to the ASP.NET web pages: WebDev.WebServer.EXE /path:<WWWROOT> Another optional argument is /port to specify the TCP port the web server should listen on. Especially if you have Skype running, you should use an alternative port like 8080.

And as final comment from a security perspective, you should be safe as this web server – unlike IIS in its default configuration – only listens for local connexions (bound to 127.0.0.1:<PORT>) and cannot be accessed remotely.
