Timeline for Official Responses API Support in .NET SDK

[buddhikaprasad]

I see that the latest .NET SDK includes Responses API support, but it’s currently marked as experimental.

Since the Responses endpoint is now the recommended way forward (replacing older Assistants/Chat APIs), I’d like to know:

What’s the timeline/ETA for promoting Responses from experimental to stable in the .NET SDK?

Are there any breaking changes expected between the experimental implementation and the stable one?

Should we start building production features on top of the current experimental Responses API, or wait until it’s officially stable?
