Understanding UAP and Building Universal Apps With Blend 2015

Introduction

 
In this article, we will learn about Understanding UAP and Building Universal Apps With Blend 2015.
 

Universal App Platform

 
 
Figure 1
 
This is a collection of Contracts and Versions that are a set of low-level APIs exactly against that a developer will be writing their apps. Every time one has Windows 10 installed, they can go ahead and check out this file that will provide them an idea of what UAP versions are supported.
 

Windows as a Service

 
This is exactly where the fun begins. The APIs in UAP is a converged set that will be the same irrespective of the platform of Windows or the Version of Windows the developer is trying to deploy. The APIs are nothing but the superset of the same that we used in Windows 8.1. Now, since “Windows as a service” will have regular updates the developers will not have an issue to migrate their solution every time. They can simply build it against the UAP that will fit correctly with all the upgrades.

Layout of Applications

 
The fundamental of laying the application has not changed. Although there are a few new tags but the Package.appxmanifest remains unchanged. There is just one single HEAD project because since in Windows 10 we will target multiple platforms against one single Windows Core. There is no family-specific binary for each of them. But yes, developers can choose to have multiple Heads that can easily go the shared project style. This can be completely done by them.
 

Laying out the Interface

 
The XAML-based UI remains exactly what it used to be. There has been a major focus on-
  1. Reusability
  2. Quality
  3. Value
  4. Scalable
  5. Accessible
Let's start by making a sample application using Blend and making the full use of the UAP.

Exploring Blend and Merits of UAP

  1. Blend now uses the same Visual Studio shell that enables the developers to have the same capabilities in terms of IntelliSense, auto-complete inside and much more.
  2. The blend has Data Management and Resource Management that are a few unique things that Blend must do itself that has been brought forward to Visual Studio 2015.
  3. UAP has made it possible to have one single binary across all the platforms of Windows.
