Xamarin studio windows phone 83/14/2023 I've attached a PDF to this lecture with additional details about setting up your Android or iOS device for development. So you simply select it and then press control F5 to deploy and run the app on your device or F5 to debug it, and these are the shortcuts that we always use in C# development. If you want to deploy and debug your application on a real device, you need to set it up for development first and then you can see it listed here. But in my case, because I'm running Windows in a virtual machine on a Mac, I had to manually install Android emulators. So if everything goes well during the installation, you should see quite a few emulators here. These emulators come as part of installing Xamarin. Here on the toolbar, we can see the list of emulators installed on my machine. So if I press control and F5, it's going to be loaded in an Android emulator. We can see that, currently, HelloWorld.Droid is set as the startup project. So you just add a project to your solution and you're good to go. Then under iOS, expand it, Universal, and here is the blank App template. We can simply delete these projects here, and if in the future you decide to support them, we can simply right-click the Solution, add a new project. Also, let's say you only want to build an app for Android and don't care about other platforms. Now if you don't have a Mac, you're not going to see this iOS project here. All these projects you see here have a reference to this class library. That's why we do most of our work in the portable class library. You want to write code that can run across different platforms. Now as I explained before, the whole idea about Xamarin Forms is about code reuse. So any time you want to write platform-specific code, we'll write it in these projects. Next, we have five platform-specific projects: one for Android, one for iOS, one for Universal Windows apps which can run on Windows 10 or Windows 10 mobile, and one for Windows 8.1, and the last one for Windows Phone 8.1. And if you look inside, we only have one class: App, which is the starting point of our application. So all the code that should be shared across different platforms should be written here. The first one is our portable class library, and this is where we're going to do most of the work. So in this solution, we have six projects. OK, all the packages are updated properly. OK, as part of this update process, one of the older packages is going to be uninstalled, and for that you need to restart Visual Studio. Then go to the Updates tab and make sure to select all packages and update them because Xamarin frequently releases new libraries. Now before looking at the structure of this solution, as a best practice, whenever you create a new Xamarin Forms app, right-click the Solution and go to Manage NuGet Packages for Solution. A Universal Windows app can run under Windows 10 or Windows 10 Mobile without the need to be rewritten for each. OK, next we're gonna see this dialogue where we select the target and minimum version for Universal Windows apps. Now this process is gonna take a few seconds so I'm gonna pause the recording. I'm gonna call our application "HelloWorld." OK. So let's go ahead with this portable class library. If you want to understand the differences between these two project types, I've attached a PDF for you for further reading, but read it after watching this video. The preferred way and the best practice recommended by Xamarin is a portable class library. For Xamarin Forms apps, we have two options here: portable class library or shared assets. ![]() Under Visual C# Templates, select Cross-Platform. ![]() Whether you're a Windows or a Mac user, watch this video thoroughly. In this video, I'm gonna show you how to create a Xamarin Forms app in Visual Studio.
