![]() Exactly like any background task, they are stored in a separate project of our solution, which will be installed together with the main app that registers it. , which includes the code to execute when the task is triggered. Let’s know more about them.Īpp services, from a code point of view, are nothing else than a background task: they are Windows Runtime Components, which contain a class that implements an interface called ![]() Which is a new feature introduced in Windows 10. The communication between the two worlds will be handled by something called At the same time, we’ll integrate a Windows Forms application, that will take care of displaying a Win32 form where the user will be able to insert some data and pass it to the UWP app. In this post we’re going to see a possible solution for this scenario: we’ll start migrating our solution to a real UWP app, so that we can leverage all the modern features offered by the platform. Or maybe your application has a very complex form, that would take a lot of time to be fully converted as UWP, but you don’t want it to be a blocker for starting to deploy the work you have done so far with the UWP app. However, as we’ve seen in the previous posts, the Universal Windows Platform may have some limitations (for security and performance reasons) that may not play well with the requirement of our business application. In all these cases, creating a UWP app can solve many challenges: for example, Windows 10 has many built-in mechanisms that make easier to create user interfaces that are automatically optimized for touch screen devices, traditional mouse & keyboard computers, inking or gaming controllers. Or maybe you are the maintainer of a big enterprise application and your customers have started to show interest in using it not just on standard desktop computers, but also in mobility using tablets and smartphones. Let’s say that, after having started to play with the Universal Windows Platform, you’ve understood its potential and how easy can be to achieve some complex tasks, like using XAML to create modern and delightful user interfaces that can automatically scale on new devices with very high resolution and DPIs. ![]() There are many scenarios where this approach can be very helpful. ![]() However, only when it’s running on a desktop, the UWP app, at some point, will be able to communicate with a Win32 process. In this case, instead, we won’t start from a traditional installer, a package folder manually converted into an AppX or a Desktop to UWP deployment project in Visual Studio 2017, but the main protagonist will be a real UWP app, capable of running on all the existing Windows 10 devices, like computers, phones, Xbox One, etc. The biggest difference, compared to the other approaches, is that, in all the past scenarios, the desktop application was the main protagonist, while the Universal Windows Platform was the sidekick that helped our Win32 process to achieve more. In this new article we’re going to see a new and different approach in the migration: how to integrate a full Universal Windows Platform app with a Win32 process. Taking an existing Win32 application and expanding it, by adding a UWP component like a background task. Taking an existing Win32 application and enhancing it, by adding UWP APIs to send toast notifications, update the live tile, use the Speech APIs, etc. Taking an existing Win32 installer and converting it into an AppX package through the Desktop App Converter tool or by leveraging manual conversion In the last posts we’ve seen, so far, three different approaches to use the Desktop Bridge:
