Problem trying to run a Web Application using Visual Studio 2013 Preview


I'm putting this here in the hope of saving some other poor soul the hour I lost this afternoon while playing around with a fresh Visual Studio 2013 Preview installation (Visual Studio Version 12).

I created a new Web Application (MVC Template) and pressed F5 to start it in debug mode.

Launch a new web application from within Visual Studio
 I was immediately presented with the following error dialog from within Visual Studio.

Microsoft Visual Studio.  
Process with an Id of xxxx is not running. 




   
I also saw the following text in my debug console window: The program '[xxxx] iisexpress.exe' has exited with code 0 (0x0)

The problem turned out to be an incorrect configuration for an IIS Express application pool setting which I found in my \users{your username}\mydocuments\IISexpress\config applicationhost.config configuration file.

The managedRuntimeVersion was mis-configured by default
I needed to change the framework version for the default app pool to match the current framework version that is installed for .NET 4.  In my case, that meant changing the version to v4.0.30319.
