Publishing Your App (App Packaging)
Uno Platform provides integrated, automated packaging for every supported platform, covering desktop, mobile, web, and embedded, with no third-party tools or extra setup required.
Packaging is part of the standard .NET publish workflow, so you can go from code to distributable packages in a single command.
Why It Matters
App packaging is the bridge between a working build and an installable application. Each OS has unique signing, metadata, and distribution requirements, which can make deployment complex for cross-platform projects.
Typical tasks include:
- Building and publishing binaries
 - Generating assets and manifests
 - Applying code signing and notarization
 - Assembling installable formats (MSIX, .app, APK, IPA, etc.)
 - Preparing for distribution or app store submission
 
Traditionally, .NET developers rely on custom scripts or third-party tools to manage this complexity. Uno Platform automates it out of the box.
The Broader Platform Packaging Ecosystem
| Platform | Formats | Signing | Distribution | Complexity | 
|---|---|---|---|---|
| Windows | MSIX, MSI, ClickOnce | Certificates | Microsoft Store, Direct | Multiple formats; Store validation | 
| macOS | .app, .pkg, .dmg | Apple certs + notarization | App Store, Direct | Mandatory notarization; complex signing | 
| Linux | Snap, AppImage, DEB, RPM | Optional | Snap Store, Direct | Multiple package managers | 
| Android | APK, AAB | Keystore | Google Play, Direct | AAB for Play; Keystore management | 
| iOS | IPA | Provisioning profiles | App Store, TestFlight | Strict signing; Profile management | 
| WebAssembly | Static files, PWA | HTTPS / CSP | Web hosting | Service workers; PWA manifest |

Key Features
- Native 
dotnet publishIntegration – No separate tools required. Works with your CI/CD pipelines. - Cross-Platform Build Support – Build Windows packages from Linux or macOS, and vice versa.
 - Advanced Publishing Options – Self-contained deployments, single-file packaging, Native AOT (where supported).
 - Automated Everything – Manifest generation, asset resizing, signing, and platform-specific optimization.
 
Example command for Android AAB:
dotnet publish -f net9.0-android -p:AndroidPackageFormat=aab
The same command pattern applies to Windows, macOS, Linux, iOS, and WebAssembly.
Preparing
Before publishing, make sure your app is optimized:
