Working with resolutions can be a real pain with WinRT apps. The MS framework isn’t as far developed as we wish sometimes. Getting the “real” resolution on a device depends on several factors.
- Does the device supports software buttons
- Do we display the titlebar
- Which scale factor is currently active
- The orientation of the device
- DPI
All in all it can be a little bit tricky to get the desired value out of the framework.
Feel free to use or modify my helper class to handle those issues.
