Initialization

Call Super.UseDrawnUi().Build() once before creating windows or canvases:

Super.UseDrawnUi()
    .ConfigureFonts(fonts =>
    {
        fonts.AddFont("fonts/Orbitron-Regular.ttf", "FontGame");
    })
    .Build();

Font files must be present next to the executable at runtime. Mark them as content with CopyToOutputDirectory:

<ItemGroup>
  <Content Include="fonts\**">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </Content>
</ItemGroup>
