Note regarding the new-api-needs-documentation label:

This serves as a reminder for when your PR is modifying a ref *.cs file and adding/modifying public APIs, to please make sure the API implementation in the src *.cs file is documented with triple slash comments, so the PR reviewers can sign off that change.

Here are the remaining items I plan to address for preview 4 in follow-up PRs

  • Add the rest of the new JsonSerializer + System.Net.Http.Json methods / make diagnostic messages localizable
  • Add more tests (All existing features are supported in this PR - except support for all collections; parameterized ctors; some edge cases with JsonInclude)

Other work items I'm tracking for post-preview 4:

Thanks folks for the review. I'm still addressing feedback. I'll merge it when it's ready and go to Tactics / back-port to preview 4.

Did you see any major performance regression since this happens every build?

I really haven't done much build-time throughput testing, but [really] early code-gen perf numbers suggested the build time isn't increasing by a crazy amount. Do you know of a reliable way to measure the perf here that doesn't include noise from other parts of the compilation?

I've taken a note to optimize the generator's implementation (e.g. looking at caching where possible), and also to adopt the incremental source generator pattern being designed.
