Deploying .NET MAUI Applications

This section guides you through the process of packaging and deploying your .NET MAUI applications to various target platforms. Understanding the deployment mechanisms for each platform is crucial for reaching your users effectively.

Introduction to MAUI Deployment

.NET MAUI applications can be deployed as standalone executables or packaged for distribution through app stores. The deployment process typically involves building a release version of your app, signing it with appropriate certificates, and packaging it in a platform-specific format.

Deploying to Windows

Windows deployment involves creating an installer package that can be easily installed by users.

Packaging for Windows

You can package your MAUI application for Windows using MSIX. This modern packaging format provides a reliable and efficient way to deploy your apps.

To create an MSIX package:

1. Ensure your project is configured for release builds.
2. Use the .NET CLI command: dotnet publish -f net8.0-windows -c Release /p:GenerateMSIXPackage=true
3. This will generate an MSIX file in your publish output directory.

Distributing via Microsoft Store

For wider distribution, you can submit your MSIX package to the Microsoft Store. This involves creating an application package in the Windows Partner Center.

Side-loading on Windows

You can also side-load your application by directly installing the generated MSIX package on any Windows 10/11 machine.

Deploying to macOS

Deploying to macOS involves creating a `.app` bundle that can be signed and distributed.

Packaging for macOS

MAUI applications for macOS are built as `.app` bundles. You can publish your app using the .NET CLI:

dotnet publish -f net8.0-maccatalyst -c Release

This will create a macOS application bundle in your publish output.

Distributing via Mac App Store

To distribute through the Mac App Store, you'll need to use Xcode and follow Apple's submission guidelines. This often involves creating an archive of your app.

Direct Distribution

You can sign your `.app` bundle with an appropriate developer certificate and distribute it directly to users.

Deploying to Android

Android deployment typically involves creating APK or App Bundle files.

Generating an APK

An APK (Android Package Kit) is the traditional format for distributing Android apps. You can generate a signed APK:

dotnet publish -f net8.0-android -c Release /p:AndroidPackageFormat=apk

Generating an Android App Bundle

Android App Bundles are the recommended format for publishing to Google Play. They allow Google Play to optimize delivery for different device configurations.

dotnet publish -f net8.0-android -c Release /p:AndroidPackageFormat=aab

Distributing via Google Play Store

Upload your signed APK or App Bundle to the Google Play Console to distribute your app to millions of users.

Deploying to iOS

iOS deployment requires signing your app with an Apple Developer certificate and provisioning profile.

Generating an IPA

An IPA (iOS App Store Package) is the file format for distributing iOS apps. You can generate an IPA using Visual Studio for Mac or the .NET CLI.

dotnet publish -f net8.0-ios -c Release

This command will produce an IPA file, typically found in the `bin/Release/net8.0-ios/` directory.

Distributing via App Store

To distribute through the Apple App Store, you will need to use Xcode and the App Store Connect portal. This involves archiving your app and uploading it for review.

Ad Hoc Distribution

For testing or limited distribution, you can use Ad Hoc provisioning profiles, which allow your app to be installed on specific registered devices.

Deploying to Linux

.NET MAUI supports targeting Linux. You can publish your Linux application using the .NET CLI:

dotnet publish -f net8.0-linux -c Release

This will generate a self-contained executable for Linux. You may need to bundle it with its dependencies for distribution.

Deployment Troubleshooting

Deployment can sometimes present challenges. Here are some common issues and their resolutions:

• Code Signing Errors: Ensure your certificates and provisioning profiles are valid and correctly configured.
• Platform-Specific Dependencies: Verify that all required runtime dependencies are included or available on the target system.
• UI Scaling Issues: Test your application on various screen sizes and resolutions to ensure proper UI rendering.
• Performance Bottlenecks: Profile your application to identify and address performance issues before deployment.
