In some limited scenarios, it might be worth switching to static readonly properties (perhaps backed by the private constant) so that updates to the library providing the ThisAssembly don't require recompiling callers in order to get the updated values (since consts are embedded raw in the callsite at compile-time).

This might not be so common since ThisAssembly is (by default) internal and (m

1. readonly is (was) slower in runtime in .net for sure.
2. C# is more like Rust, than Haskell. so mutable structs are OK. as soon as they are not shared across threads, and they are not as these are copy only. so it is safe and better design to make value mutable and allow more patterns of code to work.
3. sure, validate on set.

Currently, GraphQL.Tools just support reading schema from .gql files.
We can add the ability to read from 3rd party services like GraphQL Playground.

And do something at gen-time? Not sure what you can do.

README already has examples as partial obviously but they're easily missed.
