Some Windows 10 users report experiencing issues in the past few months while installing Microsoft Store and UWP apps, including Adobe XD – a UWP application. In today's publication, we will try to suggest a solution to this problem.
In a nutshell, Universal Windows Platforms (UWP) apps – formerly Windows Store apps and Metro style apps are apps that can be used on all compatible Microsoft Windows devices, including personal computers (PCs) , tablets, smartphones, Xbox One, Microsoft HoloLens and Internet of Things (IoT).
Essentially, a UWP application is:
- Secure: UWP apps declare device resources and the data they access. The user must authorize this access.
- Able to use a common API on all devices running Windows 10.
- Able to use device-specific capabilities and adapt the user interface to the device's different screen sizes, resolutions and DPI.
- Available from the Microsoft Store on all devices (or only those you specify) that run on Windows 10. The Microsoft Store offers several ways to make money on your app.
- Can be installed and uninstalled without risk to the machine or without incurring "machine rot".
- Interesting: use dynamic thumbnails, push notifications, and user activities that interact with the Windows timeline and Cortana's Pick Up Where I Left Off, to engage users.
- Programmable in C #, C ++, Visual Basic and Javascript. For the user interface, use XAML, HTML or DirectX.
