When I set a break-point in my JavaScript code in the browser's debugger provided by its developer tools plug-in, I get a message saying that one or more processes are already attached to this, so it can't set a break-point or debug the code in the browser.
I know that if I run a deployed app, since it is not running in the Visual Studio environment, I can attach it to the browser's debugger.
But how do I debug an app already running in Debug mode inside Visual Studio / Visual Web Developer 2010 Express inside the browser?
