minor comment on the parsable interface definition.
I also believe the generation code should be updated to implement the discriminator method generation.

Thanks for making the changes. I believe the http and json serialization manifests need to be updated to require the new version of abstractions, as well as the generation code.
@baywet Currently, package versions for the Kiota dependencies are not hardcoded, therefore on install it will fetch the latest version.

@samwelkanda thanks for the great stride here! linked the issues from the other PRs since they get closed only if the PR targets the main branch. I know serialization json is failing, I believe it's because it depends on changes made in abstractions that haven't been published yet. Ready to merge when you are.
