Summary
This post addresses a specific troubleshooting issue with launching XAML-based Windows Store apps using Coded UI Test in Windows 10. It explains that the automationID returned by the Coded UI Test engine has changed in Windows 10, causing a 'Package was not found' exception when using the XamlWindow.Launch() API. The post provides a workaround by stripping the 'tile-' prefix and '_b3rhdqcqv1gj2!App' postfix from the reported automationID to successfully launch the application.
