You can get serialization to work, but you have to use a serialization framework that is trimming compatible. For example, to use System.Text.Json, you have to opt-in the types you want to serialize.

"Opt-in" is not doing this feature justice, that is full serialization code pre-generated at compile time for your types. Beautiful.
