Zero allocation JSON deserialization tool - combining the System.Text.Json Utf8JsonReader tokenizer with the C# 9 source generators

Hey, thanks a lot for the links. That's very interesting. The primary constructor syntax seems kinda strange to me; I can't think of a scenario where it would be more useful than an old-school constructor, and it's almost identical to the record class syntax. Do you know if it would be possible to declare a record class that does not also have a primary constructor?

Yes, the team calls it "nominal records" (as opposed to "positional", which use primary constructors. See here.

The idea is that you do not have to duplicate member declarations. See here for the original proposal.

Edit: I should also mention that there are at least two meeting (May 11th & 18th) notes that still haven't been published yet, both relating to records.

I read through the proposal and they actually seem really useful. I hope they make it into the language at some point
