This guide provides a comprehensive set of interview questions and answers to help you prepare for your next UWP interview.
This guide covers a wide range of UWP interview questions, from basic concepts to advanced topics It also includes real-world scenarios and practical tips to help you showcase your skills and knowledge
Top UWP Interview Questions
1. What is the Universal Windows Platform (UWP)?
The UWP is a Microsoft platform that lets app developers make and share apps for Windows desktop computers. It gives Windows PCs, tablets, phones, and other Windows devices a single API surface.
2. What are the key benefits of using the UWP?
The UWP offers several benefits, including:
- Unified API surface: Develop once and deploy across different Windows devices.
- Rich set of APIs: Access a wide range of APIs for various functionalities, including UI, data access, networking, and more.
- Modern development experience: Leverage modern development tools and languages like C#, C++, and JavaScript.
- Built-in security features: Benefit from built-in security features like sandboxing and app isolation.
3. What are the different types of UWP apps?
There are two main types of UWP apps:
- Packaged apps: These apps are distributed through the Microsoft Store and require users to install them.
- Unpackaged apps: These apps are not distributed through the Microsoft Store and can be sideloaded onto devices.
4. What are the different lifecycles of a UWP app?
A UWP app has four main lifecycles:
- Not Running: The app is not running and is not in memory.
- Running: The app is running and is in memory.
- Suspended: The app is suspended and is not in memory, but can be resumed quickly.
- Terminated: The app is terminated and is no longer in memory.
5. What are the different ways to handle data in a UWP app?
UWP apps can handle data using various methods, including:
- Local storage: Store data locally on the device using files, folders, or the application data folder.
- Cloud storage: Store data in the cloud using services like Azure Storage or OneDrive.
- Databases: Use databases like SQLite or SQL Server to store and manage data.
6. What are the different ways to handle networking in a UWP app?
UWP apps can handle networking using various methods, including:
- HTTP: Use the HTTP protocol to communicate with web services or APIs.
- Sockets: Use sockets to establish direct connections with other devices or servers.
- WebSockets: Use WebSockets for real-time communication with web services or APIs.
7. What are the different ways to handle UI in a UWP app?
UWP apps use XAML to define their UI. XAML is a declarative language that allows developers to describe the structure and appearance of their app’s UI.
8. What are the different ways to handle navigation in a UWP app?
UWP apps can use various navigation mechanisms, including:
- Frame navigation: Use a Frame control to navigate between different pages in your app.
- Hyperlink navigation: Use hyperlinks to navigate to different pages or websites.
- Custom navigation: Implement custom navigation logic using events and code.
9. What are the different ways to handle background tasks in a UWP app?
UWP apps can use background tasks to perform tasks even when the app is not in the foreground. Background tasks can be used for various purposes, such as fetching data, processing information, or sending notifications.
10. What are the different ways to handle security in a UWP app?
UWP apps have built-in security features, including sandboxing and app isolation. Developers can also implement additional security measures, such as data encryption and authentication.
Additional Tips for UWP Interviews

Extension SDKs expose the unique capabilities of specific device types
Your app will be able to run on any device with Windows 10 or later if you use the universal APIs. But you can also make your UWP app use APIs that are only available on certain devices.
Extension SDKs let you call specialized APIs for different devices. If your UWP app is meant for an Internet of Things (IoT) device, for example, you can add the IoT extension SDK to it to target features that only work on IoT devices. For more information about adding extension SDKs, see the Extension SDKs section in Programming with extension SDKs.
You can write your app so that it will only work on a certain kind of device, and then the Microsoft Store will only let that kind of device get it. You can also check for the presence of an API during runtime and change how your app works if it finds one. For more information, see the Writing code section in Programming with extension SDKs.
There’s one store for all devices
With a unified app store, your app can be used on PCs, tablets, Xbox, HoloLens, Surface Hub, and Internet of Things (IoT) devices. By putting your app in the store, you can make it work on any device or just the ones you pick. You submit and manage all your apps for Windows devices in one place. Do you want to bring your old C desktop app up to date with UWP features and sell it in the Microsoft Store? That’s fine too.
UWP apps integrate with Application Insights for detailed telemetry and analyticsâa crucial tool for understanding your users and improving your apps.
UWP apps can be packaged with MSIX and distributed via the Microsoft Store, or in other ways. Apps can be updated through MSIX no matter how they are shared (see Update non-Store published app packages from your code for more information).
You can choose how youll monetize your app. There are a number of ways to make money with your app. All you need to do is choose the one that works best for you, for example:
- A paid download is the simplest option. Just name the price.
- Trials let people try out your app before they buy it, which makes it easier for people to find and buy than “freemium” options.
- Sale prices to incentivize users.
- In-app purchases.
