Getting Started

Important

The documentation is minimal, but the demo project showcases all available features. This library is designed to be very developer-friendly.

1. Install the NuGet package

Install-Package Message.Avalonia

2. Add the required styles to your App.xaml

<Application ...
             xmlns:msg="https://github.com/xiyaowong/Message.Avalonia"
             ...>

    <Application.Styles>
        <msg:Theme />
    </Application.Styles>
</Application>

3. Add the MessageHost to your UI layout

<Panel>
    <!-- Your main UI content -->
    <msg:MessageHost />
    <msg:MessageHost HostId="Another" Position="BottomCenter" />
</Panel>

• HostId is optional. If omitted, the default host will be used.
• You can skip defining MessageHost entirely — a default host will be created automatically if needed.

4. Show messages using MessageManager

MessageManager.Default.ShowInfomationMessage("Hello");
