Early test shows upto 50% reduction (50mb -> 25mb) with the following Default.md file:

    <!--<Assembly Name="*Application*" Dynamic="Required All" />-->
    
    <!-- .NET Native fix -->
    <Assembly Dynamic="Required All" Name="NLog"/>
    <Assembly Dynamic="Required All" Name="Microsoft.Extensions.DependencyInjection"/>
    <Assembly Dynamic="Required All" Name="Microsoft.Extensions.Options"/>
    <Assembly Dynamic="Required All" Name="Microsoft.Extensions.Logging"/>
    <Assembly Dynamic="Required All" Name="Microsoft.Extensions.Http"/>

Problem is serializers returning null due to reflection, will need to rewrite using source generator:
https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/source-generation

I was suggested to use System.Text.Json 8.0 Preview 1 for better source generators.

Sample:

[JsonSourceGenerationOptions(PropertyNameCaseInsensitive = true)]
[JsonSerializable(typeof(AirQuality), GenerationMode = JsonSourceGenerationMode.Metadata)]
internal partial class MyJsonContext : JsonSerializerContext
{
}
..
await JsonSerializer.DeserializeAsync(stream, MyJsonContext.Default.AirQuality);
