How to Create a Xamarin Project and Run It in an Emulator
Xamarin is a platform that allows you to build mobile applications. It’s open-source and has community support from developers and users worldwide.
you’re able to build mobile apps across various platforms, such as iOS, Android, or Windows. UI can also be specific to a platform, or shareable across platforms, depending on whether you use Xamarin Native or Xamarin Forms.
Visual Studio allows you to create a new Xamarin project and add your content to your mobile application. You can then test your mobile app by running it through the emulator.
What Are Xamarin Native and Xamarin Forms?
Xamarin Native includes Xamarin iOS, Xamarin Windows, or Xamarin Android. It allows you to build user interfaces for a specific platform.
For example, you can use some UI components only on Android and other UI components only on iOS. This is great if you want custom designs for different platforms, but can lead to slower development.
Xamarin Forms, on the other hand, allows you to build shared UI components that you can re-use over many platforms. This is good for generic components such as buttons or text boxes that will look the same across all devices. This also generally leads to faster development.
Microsoft is currently in the process of replacing Xamarin with .NET MAUI (Multiform App User Interface), as part of .NET 6. According toMicrosoft’s .NET Blog, one of the new features is the ability to use a single project, rather than many projects across many platforms.
How to Download and Install Mobile Development for .NET
To build aMicrosoft Xamarinmobile application you need to download and installMobile Development for .NETin Visual Studio. This gives you the ability to create Xamarin projects. It also comes with anemulator to test your mobile app on a PC.
How to Create a New Xamarin Project
Once you have installed Mobile development with .NET, open Visual Studio and create a new Xamarin project.
The Basic Components of a Xamarin Application
By default, multiple projects make up a Xamarin application. TheXamarinProjectstores shared UI elements or logic. It contains theMainPage.xamlfile, which stores shared UI elements that will work for both iOS and Android devices.
TheXamarinProjectalso contains the Dependencies folder, which stores some NuGet packages. These NuGet packages include the required functions for the Xamarin project to work.
There are also two other separate projects, each for the Android and iOS platforms. If you are running the mobile app using Android, the app starts from theMainActivity.xamlfile. If you are running the mobile app using iOS, the app starts from theMain.csfile.
How to Add Content to Your Xamarin Application
Add some content to your mobile application. Xamarin includes a range of built-in elements such as labels, buttons, or boxes that you can use to build your interface.
Each element also has attributes, such as color, text, or other applicable styling. The syntax is a bit similar to how you would create HTML tags. For example:
In theMainPage.xamlfile, modify the code to add a few basic UI elements, such as a label and a button.
How to Run Your Xamarin Application Using the Android Emulator
You can run the Xamarin application using an emulator, which you can select at the top of the toolbar in Visual Studio.
Creating Mobile Applications Using Xamarin
Xamarin allows you to build Mobile applications across many platforms, such as iOS, Android, or Windows. It allows you to use UI elements that are re-usable or UI elements that you can share across many platforms.
When you create a new Xamarin project, you’re able to add your content in the available xaml and C# files. You can also test what your mobile application looks like by opening it using an emulator.
There are many courses and resources you can explore to improve your knowledge on how to build mobile applications. This also includes development courses for specific platforms, such as Android or iOS development.
