In JS interop, add Invoke/InvokeAsync overloads that use C#11 param span

[SteveSandersonMS]

Hopefully we can save one allocation per call, at least in the cases that had to use params in the past.

Thanks for contacting us.

We're moving this issue to the .NET 7 Planning milestone for future evaluation / consideration. We would like to keep this around to collect more feedback, which can help us with prioritizing this work. We will re-evaluate this issue, during our next planning meeting(s).
If we later determine, that the issue has no community involvement, or it's very rare and low-impact issue, we will close it - so that the team can focus on more important and high impact issues.

Is this still part of the C# 11 / .NET 7 roadmap? Or will it be shipped later? Because I don't find params span here

[SteveSandersonMS]

@mu88 It's still a .NET 7 candidate, however we haven't assigned it to a particular milestone as it's not clear we have capacity to do it. If you're interested in doing a PR for this, that might be what's needed to get it in on time. Otherwise I can't predict yet whether or not it will make it.

[SteveSandersonMS]

@mu88 Oh actually I see your point that the language feature itself isn't there yet. In that case it's fairly clear that it wouldn't be something we could do for Blazor!

[mu88]

Yeah that's what I mean @SteveSandersonMS - I'm happy to assist as soon as the language feature is available

Is there an approved API proposal?

It looks like this C# language feature was original proposed on this Issue: dotnet/csharplang#1757
It has now been subsumed by this Proposal issue for Parent Collections support in general dotnet/csharplang#7700
