How to use my downloaded fonts in WinUI 3?

In my WinUI 3 app, I try to declare and apply my downloaded fonts but it doesn't work.

Note: If I manually install the font on my computer, it works well. I wonder if the font installation is a must-have step in WinUI 3?

Steps that I have done

Add fonts .tff file to myapp/Assets/Fonts
Add resource dictionary:

   <ResourceDictionary>
       <FontFamily x:Key="DancingScriptBold">/Assets/Fonts/DancingScript-Bold.ttf/#Dancing Script</FontFamily>
   </ResourceDictionary>

Apply to my custom textblock style:

                       <Style x:Key="Body1" TargetType="TextBlock">
                           <Setter Property="FontSize" Value="14" />
                           <Setter Property="FontFamily" Value="{StaticResource DancingScriptBold}" />
                       </Style>

I wonder if the font installation is a must-have step

If you want to use a font in any app, also like Ofiice/Word, then installing the font on the machine is always a must-have.

I'm experiencing the same problem. Even tried signed fonts from c:\Windows\Fonts, made sure that the font Title is the correct one after #. The resource dictionary compile without error and the static resources are immediately available in the Xaml editor. However, at run time the FontFamily is ignored, and the default font is used. I made sure that the fonts are declared Content and are copied to the output directory. I don't know what else can be wrong in my code.

In App.xaml:

<Application
    x:Class="SCControlApp.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
                <ResourceDictionary Source="/Styles/FontSizes.xaml" />
                <ResourceDictionary Source="/Styles/Thickness.xaml" />
                <ResourceDictionary Source="/Styles/TextBlock.xaml" />

                <ResourceDictionary>
                    <FontFamily x:Key="LCD">/Fonts/LCD14.ttf#LCD</FontFamily>
                    <FontFamily x:Key="ArialRB">C:/Windows/Fonts/ARLRDBD.TTF#Arial Rounded MT Bold</FontFamily>
                    <FontFamily x:Key="FelixTI">C:/Windows/Fonts/FELIXTI.TTF#Felix Tiling</FontFamily>
                </ResourceDictionary>

            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

Then in my window Xaml

                <StackPanel VerticalAlignment="Center" HorizontalAlignment="Center" Spacing="20">
                    <TextBlock Name="LatText" FontFamily="{StaticResource LCD}"     FontSize="32" Text="12:34:56.00 N"/>
                    <TextBlock Name="LonText" FontFamily="{StaticResource ArialRB}" FontSize="32" Text="123:45:59.00 W"/>
                    <TextBlock Name="HgtText" FontFamily="{StaticResource FelixTI}" FontSize="32" Text="1250.1m" />
                </StackPanel>

But no change in the final result:
