@dotnet-policy-service agree

[huoyaoyuan]

Thank you for your interest of contribution. Adding new API like methods require going through API review process. Pull requests should not be opened before the API get discussed.

[wessleym]

@huoyaoyuan, I apologize.
#98890
As I said in my above issue, this class does not seem to be me to be a new API. It's just a new class within a larger API. But it's not clear to me what qualifies a change as being a new API.
Would you prefer I close this pull request? I am happy to do so.

[huoyaoyuan]

But it's not clear to me what qualifies a change as being a new API.

Anything new accessible from user code is new API, including public things and protected members on public types.

Once added and shipped in stable version, they can't be removed ever. (Although we still ultimately reserve the right.) Thus, every addition needs approval.

[wessleym]

I accept what you're saying, and if you'd rather I close this, I will. Would you like me to proceed with closing?
(Please note that the contribution guidelines say, "If your change adds a new API, follow the API Review Process." In other programming spheres of which I'm aware, a single class wouldn't qualify as a whole new API--more like new API functionality. So that's where my confusion arose.)

[stephentoub]

@wessleym, thanks for your interest in contributing; and yes, please close it... you're welcome to reopen if/when the API proposal is accepted. We define new APIs as any change that would show up in a reference assembly, including adding a single public method, a single new class, implementing an additional public interface on an existing class, etc.

[wessleym]

@stephentoub and @huoyaoyuan, thank you for your patience with me. I'll close this now.
