Reproduce with the generation command and the spec in the issue, then deserialize {"name":"a","size":2} to Entry using the JsonSerializerOptions from the generated HostConfiguration and serialize it back. Linked pull request #25549 is already open against this bug, so review it before starting. Done means the round trip keeps name and size and the output is no longer {}.
