WinUI uses ContextFlyout instead ContextMenu. README contains example for WPF.

Thank for getting back so quickly! Though I still can't get it to work. I'm getting following error message when running:

Cannot find a Resource with the Name/Key TrayMenu

I'm aware this is probably because I didn't define that resource nowhere. I searched the Internet and found some sample code for TrayMenu, as well as TrayStatusPopup. I put it in my App.xaml like so:

App.xaml:

<Application
    x:Class="WinUITrayTest.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:WinUITrayTest">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
                <!-- Other merged dictionaries here -->
            </ResourceDictionary.MergedDictionaries>
            <!-- Other app resources here -->
            <MenuFlyout x:Key="TrayMenu">
                <MenuFlyoutItem Text="Red" Tag="red" />
                <MenuFlyoutItem Text="Green" Tag="green"/>
            </MenuFlyout>

            <Border x:Key="TrayStatusPopup" Background="White" BorderBrush="Gray" BorderThickness="1" CornerRadius="3" Width="auto" Height="auto">
                <StackPanel>
                    <Button Name="btnSetupTray" Content="Setup" Margin="5" Width="70"></Button>
                    <Button Name="btnExitTray" Content="Exit" Margin="5" Width="50"></Button>
                </StackPanel>
            </Border>
        </ResourceDictionary>
    </Application.Resources>
</Application>

As for the last resource, I didn't define anything, because I just wanted to test it out quickly. So this exception appears when building the code:

Failed to assign to property 'H.NotifyIcon.TaskbarIcon.TrayPopup'

Also, if I can suggest. Wouldn't it be much clearer if in the README it'd be specified that for WinUI 3 apps, the property ContextFlyout should be used? I could be wrong, but I didn't find it nowhere in the repo description?

Also, I think that it'd be very useful to include some sample code for all three resources: TrayMenu, TrayStatusPopup and TrayToolTip. What do you think?

@symonxdd If you already know how to use the H.NotifyIcon you could add examples or improve README.

I thought to add examples for WinUI3 because I use it.

[HavenDV]

There are two applications here as examples: https://github.com/HavenDV/H.NotifyIcon/tree/master/src/apps/H.NotifyIcon.Apps.WinUI.Windowless https://github.com/HavenDV/H.NotifyIcon/tree/master/src/apps/H.NotifyIcon.Apps.WinUI But I agree with you that the README needs to be improved.
