Packaging Fonts with Applications - WPF .NET Framework | Microsoft Docs[^]:

In order to reference font resource items from code, you must supply a two-part font resource reference: the base uniform resource identifier (URI); and the font location reference.

<Window.Resources>
    <Style x:Key="Foo">
        <Setter Property="TextElement.FontFamily" Value="pack://application:,,,/Main;component/Fonts/#MyFont" />
    </Style>
    <Style x:Key="Bar">
        <Setter Property="TextElement.FontFamily" Value="./Fonts/#MyFont" />
    </Style>
    <FontFamily x:Key="Baz">./Fonts/#MyFont</FontFamily>
</Window.Resources>

<StackPanel Orientation="Vertical">
     <TextBlock Text="" Style="{StaticResource Foo}" />
     <TextBlock Text="" Style="{StaticResource Bar}" />
     <TextBlock Text="" FontFamily="{StaticResource Baz}" />
     <TextBlock FontFamily="Segoe MDL2 Assets" Text="" />
     <TextBlock x:Name="txt1" />
     <TextBlock x:Name="txt2" />
 </StackPanel>

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    txt1.FontFamily = new FontFamily("pack://application:,,,/Main;component/Fonts/#MyFont");
    txt1.FontFamily = new FontFamily(new Uri("pack://application:,,,/Fonts/"), "./#MyFont");
    txt1.FontFamily = new FontFamily("MyFont");
    txt1.Text = "\xe905";
}
