No Mixed Mode Debugging Support Use Multiple Instances Instead Launch the app under the script debugger Attach with the native debugger from a second instance of VS Visual Studio naturally gives focus to the correct instance Cannot Debug JavaScript when stopped in the native debugger

Windows 8 contracts provide a new entry point for applications It’s not the same code as just launching under the debugger Simply attaching is not quick enough as you may have missed the code that you wanted to debug

Configure the app to debug without launch in the project properties F5 the app Invoke your application manually through the contract

Your app can register to run background tasks when certain events happen Some background tasks are straight forward to test and debug because you can trigger them manually Others can be a much bigger pain Like a maintenance trigger that fires after 8 hours

Trigger background tasks from the Debug Location Toolbar Can trigger tasks on apps that are not running Set them to debug without launching first Can trigger tasks that do not require a payload

There are several reasons why you may not have a VS project, but still want to debug Permissions Convenience Normally build/deploy outside of VS Attach to process is a pain for WWAs Especially if you need to debug startup code!
