Understanding Universal Windows Platform With Hello World App

Background

Universal Windows platform (UWP) is a platform-homogeneous Application architecture, created by Microsoft and first introduced in Windows 10. The purpose of this software platform is to help develop metro style apps, that run on both Windows 10 and Windows 10 mobile, without the need to rewrite for each. It supports Windows Application development, using C++, C#, VB.Net, or XAML. The API is implemented in C++ and supported in C++, VB.Net, C#, F# and JavaScript. It is designed as an extension to the Windows run time platform, first introduced in Windows Server 2012 and Windows 8. The UWP allows developers to create applications that will potentially run on multiple types of devices. (source: wikipedia)

We can easily develop UWP apps with the help of API packages and run them on all Window 10 devices including phone, desktop, tablet and so on. It also supports a number of screen resolutions.

Prerequisites

We are going to discuss how to develop, build and run the UWP Hello World App and show the demo in multiple devices. We will see the step by step guidelines for the UWP Hello World app creation here:

Step 1

Open Visual Studio 2015. Go to file menu, point to new and then click new project. New Project window will open. You can select an installed template like “ Universal” under Windows in Visual C# Template and then select a blank app universal Windows, and type Project Name UWPHelloWorld. Choose the project location path and then click OK button.



Now, you can see UWPHelloWorld project structure, shown in the screen shot:
