Building and testing Xamarin applications

You can create a continuous integration (CI) workflow in GitHub Actions to build and test your Xamarin application.

GitHub Actions ist verfügbar mit GitHub Free, GitHub Pro, GitHub Free für Organisationen, GitHub Team, GitHub Enterprise Cloud, und GitHub AE. GitHub Actions ist nicht verfügbar für private Repositorys, die im Besitz von Konten mit älteren Pro-Repository-Plänen sind.

Note: GitHub Actions was available for GitHub Enterprise Server 2.22 as a limited beta. The beta has ended. GitHub Actions is now generally available in GitHub Enterprise Server 3.0 or later. For more information, see the GitHub Enterprise Server 3.0 release notes.


Note: GitHub-hosted runners are not currently supported on GitHub Enterprise Server. You can see more information about planned future support on the GitHub public roadmap.

Einführung

This guide shows you how to create a workflow that performs continuous integration (CI) for your Xamarin project. Der Workflow, den Du erstellst, zeigt Dir, wenn Commits zu einem Pull-Request zu Build- oder Testfehlern für deinen Standard-Zweig führen. Dieser Ansatz kann dazu beitragen, dass Dein Code immer brauchbar ist.

For a full list of available Xamarin SDK versions on the GitHub Actions-hosted macOS runners, see the documentation:

Note: The macOS 11 virtual environment is currently provided as a private preview only. Any users or organizations that are already using this runner can continue using it, but we're not accepting any further users or organizations at this time. The macos-latest YAML workflow label still uses the macOS 10.15 virtual environment.

Vorrausetzungen

We recommend that you have a basic understanding of Xamarin, .NET Core SDK, YAML, workflow configuration options, and how to create a workflow file. Weitere Informationen findest Du unter:

Bulding Xamarin.iOS apps

The example below demonstrates how to change the default Xamarin SDK versions and build a Xamarin.iOS application.

name: Build Xamarin.iOS app

on: [push]

jobs:
  build:

    runs-on: macos-latest

    steps:
    - uses: actions/checkout@v2
    - name: Set default Xamarin SDK versions
      run: |
        $VM_ASSETS/select-xamarin-sdk-v2.sh --mono=6.12 --ios=14.10

    - name: Set default Xcode 12.3
      run: |
        XCODE_ROOT=/Applications/Xcode_12.3.0.app
        echo "MD_APPLE_SDK_ROOT=$XCODE_ROOT" >> $GITHUB_ENV
        sudo xcode-select -s $XCODE_ROOT

    - name: Setup .NET Core SDK 5.0.x
      uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '5.0.x'

    - name: Install dependencies
      run: nuget restore <sln_file_path>

    - name: Build
      run: msbuild <csproj_file_path> /p:Configuration=Debug /p:Platform=iPhoneSimulator /t:Rebuild

Bulding Xamarin.Android apps

The example below demonstrates how to change default Xamarin SDK versions and build a Xamarin.Android application.

name: Build Xamarin.Android app

on: [push]

jobs:
  build:

    runs-on: macos-latest

    steps:
    - uses: actions/checkout@v2
    - name: Set default Xamarin SDK versions
      run: |
        $VM_ASSETS/select-xamarin-sdk-v2.sh --mono=6.10 --android=10.2

    - name: Setup .NET Core SDK 5.0.x
      uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '5.0.x'

    - name: Install dependencies
      run: nuget restore <sln_file_path>

    - name: Build
      run: msbuild <csproj_file_path> /t:PackageForAndroid /p:Configuration=Debug

Specifying a .NET version

To use a preinstalled version of the .NET Core SDK on a GitHub-hosted runner, use the setup-dotnet action. This action finds a specific version of .NET from the tools cache on each runner, and adds the necessary binaries to PATH. These changes will persist for the remainder of the job.

The setup-dotnet action is the recommended way of using .NET with GitHub Actions, because it ensures consistent behavior across different runners and different versions of .NET. If you are using a self-hosted runner, you must install .NET and add it to PATH. For more information, see the setup-dotnet action.
