Build your first hybrid app

  • Article

Important

This project is an experimental release. We hope you try out Experimental Mobile Blazor Bindings and provide feedback at https://github.com/xamarin/MobileBlazorBindings.

The easiest way to get started with Experimental Mobile Blazor Bindings to build hybrid apps is to create the initial project from the command line. This template supports creating apps for Android, iOS, WPF (Windows), and macOS.

Note

If you have not yet done so, check the pre-requisites and template installation instructions.

  1. Open a command prompt or shell window

  2. Create your project by running this command:

    dotnet new blazorhybrid -o FirstBlazorHybridApp

    This will create a folder named FirstBlazorHybridApp with the solution file (SLN) and five projects in sub-directories:

    1. FirstBlazorHybridApp/FirstBlazorHybridApp.csproj - this is the shared project that will contain the hybrid UI and logic of your application. That is, it will contain both native UI and web UI all using Razor syntax.
    2. FirstBlazorHybridApp.Android/FirstBlazorHybridApp.Android.csproj - this is the "backend" project for targeting Android devices. On Windows or Mac you can run this project to launch the app in the Android Emulator.
    3. FirstBlazorHybridApp.iOS/FirstBlazorHybridApp.iOS.csproj - this is the "backend" project for targeting iOS devices. On Mac you can run this project to launch the app in the iOS Simulator. On Windows you can run it as well if you have a Mac that is paired.
    4. FirstBlazorHybridApp.Windows/FirstBlazorHybridApp.Windows.csproj - this is the "backend" project for targeting Windows devices using Windows Presentation Foundation (WPF). On Windows you can run this project to launch the app.
    5. FirstBlazorHybridApp.macOS/FirstBlazorHybridApp.macOS.csproj - this is the "backend" project for targeting macOS devices. On Mac you can run this project to launch the app.

  3. You are now ready to open the solution in Visual Studio. To open the solution you can double-click the SLN file on your disk, or you can first open Visual Studio 2019, select File / Open / Project/Solution, and then navigate to the new folder you created and select FirstBlazorHybridApp.sln. The solution in Visual Studio should look like this:

    Solution Explorer with all 5 projects

  4. To run the project, you'll need to set one of the "backend" projects as your startup project. In Solution Explorer, right-click on the Android, iOS, Windows, or macOS project and select Set as StartUp Project.

    Set startup project in Solution Explorer

  5. Press F5 to launch the project in the emulator or on a device (depending on the chosen project) with the debugger attached (or press Ctrl+F5 to run without the debugger)

    • Tip: If you want to run the iOS project on the iOS Simulator, ensure that you select the iPhoneSimulator target from the Visual Studio toolbar instead of iPhone.

  6. Your first application will launch in an emulator or on a device and look like this:

    Hello World hybrid app running in the iOS Simulator

  7. Congratulations, you've created and run your first Experimental Mobile Blazor Bindings hybrid app!
