Looks to be #51528. Why these new APIs aren't getting trimmed, I don't know.

@DrewScoggins how can I get more recent readings on individual file sizes? Links like this one seem to only report aggregate sizes.

[steveharter]

I can't seem to repro. When I create a project that use other methods in S.N.H.Json.dll and publish\trim it, the new extensions (e.g.GetFromJsonAsync(JsonSerializerContext)) are not present in the HttpClientJsonExtensions static class.

Closing until we have a repro or more information on how to create a repro.
