MauiReactor is .NET library written on top of .NET MAUI that allows you to write applications in pure C# using an MVU approach.

This is the classic Counter app in MauiReactor:

class CounterPageState
{
    public int Counter { get; set; }
}

class CounterPage : Component<CounterPageState>
{
    public override VisualNode Render()
        => ContentPage("Counter Sample",
            VStack(
                Label($"Counter: {State.Counter}"),

                Button("Click To Increment", () =>
                    SetState(s => s.Counter++))
            )
            .Spacing(10)
            .Center()
        );
    
}

1. Install MauiReactor templates

dotnet new install Reactor.Maui.TemplatePack

2. Install MauiReactor hot reload console command

dotnet tool install -g Reactor.Maui.HotReload

If you already installed an old version of Reactor.Maui.HotReload you can update it to the latest using this command:

dotnet tool update -g Reactor.Maui.HotReload

3. Create a sample project

dotnet new maui-reactor-startup -o my-new-project

and move inside the new project folder

cd .\my-new-project\

4. Build & run the project (emulator or device must be running and configured)

dotnet build -t:Run -f net8.0-android

Under Mac, to target an iOS device/emulator, issue a command like this:

dotnet build -t:Run /p:_DeviceName=:v2:udid=<device_id> -f net8.0-ios

where the device id comes from this list:

xcrun simctl list

5. Hot-reload console (in a different shell)

dotnet-maui-reactor -f [net8.0-android|net8.0-ios|...]

6. Edits to code should be hot-reloaded by the application --> Enjoy!
