So I resolved my issue. The Diagnostic Tools window currently does not support:
- Windows Store projects that are using JavaScript
- Windows Store projects that are running on a Windows Phone
- Debugging with Use Managed or Native Compatibility Mode
In my case I had ‘Use Managed Compatibility Mode’ enabled. To change this go to the following and uncheck the ‘Use Managed Compatibility Mode’ or ‘Use Managed Native Mode’.
Tools –> Options –> Debugging -> General -> (Un-check) ‘Use Managed Compatibility
Mode’
