SslStream ALPN support

[Perksey]

Application-Layer Protocol Negotiation (ALPN) was added in .NET Core 2.1, but not .NET Standard. Does the .NET team plan to make this a standard and, if not, why?

We're working on a HTTP/2 server library that depends on ALPN and we'd like it shipped on .NET Standard, so any info you can provide is much appreciated :)

Pretty sure everything for ALPN is in candidate PR #827

[Perksey]

Ah didn't see that, will keep an eye on that :)

@terrajobst Is there any chance for this to be back-ported to .net standard 2.0 as well?

No, that's not possible per-spec. See this question in the FAQ.
