A (unofficial) command-line tool for managing .NET MAUI release channels, inspired by the Aspire CLI. Easily switch between stable releases, nightly builds, and PR builds for your .NET MAUI projects.

✨ Features

• 📦 Stable Channel: Update to the latest stable release from NuGet.org
• 🌙 Nightly Channel: Apply nightly builds from the MAUI development feeds
• 🔧 PR Builds: Test pull request builds before they're merged
• 🎨 Interactive Mode: Beautiful, user-friendly menus powered by Spectre.Console
• ⚡ Command-Line Mode: Fully scriptable for CI/CD and automation
• 🎯 Smart TargetFrameworks: Automatically detects and prompts to update .NET versions
• 🔍 Auto-Discovery: Finds your MAUI project automatically

📥 Installation

Global Tool (Recommended)

dotnet tool install --global version-maui

Note: The package name is version-maui, but the command to run it is maui-version.

Update Existing Installation

dotnet tool update --global version-maui

Uninstall

dotnet tool uninstall --global version-maui

🎯 Quick Start

Navigate to your .NET MAUI project directory and run:

maui-version apply

The CLI will:

1. 🔍 Automatically detect your MAUI project
2. 📊 Display your current MAUI version and .NET target framework
3. 🎨 Show an interactive menu to select a channel
4. ✅ Apply the selected channel and update your project

📖 Usage

Interactive Mode (Recommended)

# Run in your MAUI project directory
maui-version apply

# Or specify the project path
maui-version apply --project ./src/MyMauiApp

Example Output:

✓ Found MAUI project: MyApp.csproj
✓ Current version: 9.0.10
✓ Target .NET version: .NET 9.0

Select a release channel:
> Stable
  Nightly
  PR Build

Command-Line Mode

Perfect for automation and CI/CD pipelines!

📦 Stable Channel

# Apply latest stable release
maui-version apply --channel stable
maui-version apply -c stable  # Short version

# With specific project path
maui-version apply --channel stable --project ./src/MyMauiApp
maui-version apply -c stable -p ./src/MyMauiApp  # Short version

The CLI automatically selects the correct stable version based on your project's TargetFrameworks.

🌙 Nightly Channel

# Apply latest nightly build (prompts for .NET version selection and TFM update confirmation)
maui-version apply --channel nightly
maui-version apply -c nightly  # Short version

# Apply nightly build with specific .NET version (auto-updates TFMs without prompting)
maui-version apply --channel nightly --target-framework net10.0
maui-version apply -c nightly -f net10.0  # Short version

# With specific project path
maui-version apply --channel nightly --project ./MyApp
maui-version apply -c nightly -p ./MyApp  # Short version

Note: When you specify -f/--target-framework, the tool will automatically update your TargetFrameworks if there's a mismatch. Without -f, the tool will prompt you for confirmation before making TFM changes.

Nightly builds come from:

• https://aka.ms/maui-nightly/index.json (combined feed)

🔧 PR Builds

Test a specific pull request before it's merged:

# Apply PR build by number (prompts for .NET version and TFM update confirmation)
maui-version apply --apply-pr 32931
maui-version apply -pr 32931  # Short version

# Apply PR build with specific .NET version (auto-updates TFMs without prompting)
maui-version apply --apply-pr 32931 --target-framework net10.0
maui-version apply -pr 32931 -f net10.0  # Short version

# With project path
maui-version apply --apply-pr 32931 --project ./src/MyApp
maui-version apply -pr 32931 -p ./src/MyApp  # Short version

Note: When you specify -f/--target-framework, the tool will automatically update your TargetFrameworks if there's a mismatch. Without -f, the tool will prompt you for confirmation before making TFM changes.

How PR Builds Work:

1. The CLI queries GitHub's Checks API for the PR
2. Finds the associated Azure DevOps build
3. Downloads the build artifacts (NuGet packages)
4. Creates a local NuGet.config pointing to the artifacts
5. Updates your project to use the PR build version

Example PRs you can test:

# Test a recent PR
maui-version apply --apply-pr 33002

Other Options

# Show help
maui-version apply --help

# Show version
maui-version --version

🔍 How It Works

📦 Stable Channel

1. Detect: Reads your project's TargetFrameworks (e.g., net9.0-android;net9.0-ios)
2. Query: Searches NuGet.org for the latest stable MAUI version compatible with your .NET version
3. Update: Modifies your .csproj to use the latest stable version
4. Clean: Removes any custom NuGet.config files to use NuGet.org defaults
5. Restore: Runs dotnet restore to download packages

Smart Version Selection: Automatically picks the right MAUI version for your .NET TFM:

• .NET 9 projects → Latest MAUI 9.x stable
• .NET 10 projects → Latest MAUI 10.x stable

🌙 Nightly Channel

1. Select: Choose your .NET version (auto-detected from TargetFrameworks)
2. Configure: Creates NuGet.config with the MAUI nightly feed
3. Version Check: Compares package .NET version with your project's TFM
4. Prompt: If mismatch detected, offers to update TargetFrameworks
5. Update: Applies the latest nightly version
6. Restore: Downloads packages from the nightly feed

Feed URL: https://aka.ms/maui-nightly/index.json

🔧 PR Build Channel

The most advanced feature! Here's how it works:

1. GitHub Integration: Queries GitHub Checks API for the PR's commit SHA
2. Build Discovery: Finds Azure DevOps builds associated with the PR
   • Supports multiple build configurations (xamarin/public, xamarin/GUID-project)
   • Works with both main build checks and sub-jobs
   • Handles draft and merged PRs
3. Download: Fetches build artifacts from Azure DevOps (no auth required for public repos)
4. Extract: Unpacks NuGet packages to a local temp directory
5. Configure: Creates a NuGet.config pointing to the local packages
6. Version Check: Detects if PR build requires a different .NET version
7. Prompt: Offers to update TargetFrameworks if needed
8. Apply: Updates your project to use the PR build version

Example Workflow:

maui-version apply --apply-pr 32931

✓ Found PR #32931 on GitHub
✓ Retrieved commit SHA: 20c776fe
✓ Found build check: MAUI-public
✓ Extracted build ID: 155100
✓ Downloading artifacts...
✓ Found MAUI version: 10.0.20-ci.main.25604.11
? Package requires .NET 10.0, but project uses .NET 9.0
? Update TargetFrameworks to .NET 10.0? (y/n)

⚙️ Requirements

• .NET 8.0 SDK or later (to run the CLI tool)
• A .NET MAUI project with:
  • <UseMaui>true</UseMaui> in the .csproj
  • Valid TargetFrameworks property (e.g., net9.0-android;net9.0-ios)
  • Microsoft.Maui.Controls package reference

🆘 Troubleshooting

"No MAUI project found in the current directory"

Solution: Make sure you're in a directory with a .csproj file that contains <UseMaui>true</UseMaui>.

# Check your current directory
dir *.csproj

# Or specify the project path
maui-version apply --project ./src/MyApp

"No successful build found for PR #XXXXX"

Possible causes:

1. The PR hasn't triggered a build yet (draft PRs sometimes don't auto-build)
2. The build is still in progress
3. The build failed
4. The PR is old and artifacts have been cleaned up

Solution: Check the PR on GitHub to verify builds completed successfully.

Nightly packages fail to restore

Solution:

1. Ensure you have internet access
2. Try clearing NuGet cache: dotnet nuget locals all --clear
3. Check the feed is accessible: https://aka.ms/maui-nightly/index.json

TargetFrameworks mismatch prompt keeps appearing

This is expected when applying a nightly or PR build that targets a different .NET version than your project.

Options:

• Choose "Yes" to update TargetFrameworks (recommended for testing)
• Choose "No" to cancel and stay on current .NET version

"Cannot show selection prompt" error

This happens when running in a non-interactive terminal.

Solution: Use explicit command-line options:

maui-version apply --channel stable --project .
