@dstelljes We are running into an issue with schemas created from .NET types where the default values that are declared on the class properties don't get translated to the schema, i.e.
public class Message
{
public int? Property { get; set; } = null;
}
generates the schema {"name":"Message","type":"record","fields":[{"name":"Property","type":["null","int"]}]}
without the default field.
Is this related to this serialization issue? I also see that this is tagged as "help wanted" and may be able to help work on it if given some direction.

It’s somewhat related—this issue specifically relates to support for "default"
values when building serializers.
Your use case is tricky because there isn’t any reliable way to get the default .NET value when building a schema: In your example, null
is assigned to Property
when Message
is constructed; it’s not a constant value that can be obtained by reflecting on the class.

What about just relying on the [DefaultValue] attribute
