Work around implicit usings breaking change

[tmat]

Work around dotnet/sdk#19521

Without this workaround Arcade update breaks builds, e.g. https://github.com/dotnet/sourcelink/pull/729/checks?check_run_id=3280200935

[markwilkie]

makes sense to me - adding @mmitche as an fyi

[dougbu]

This is going to break dotnet/aspnetcore because we are intentionally ahead of Arcade on SDK versions and have already reacted to the implicit usings change. /cc @dotnet/aspnet-build

[markwilkie]

What does it mean for y'all @dougbu when the implicit using switches to opt in instead of opt out? (that change is on the way I hear)

dotnet/sdk#19599

[Pilchie]

Tagging @DamianEdwards and @pranavkm

It means we need to flip some logic in dotnet/aspnetcore. I'm not sure if that's already happened. @wtgodbe❔

[pranavkm]

AspNetCore is on a newer SDK that no longer uses this switch. This shouldn't affect AspNetCore any more.

[RussKie]

Is this getting undone?

[markwilkie]

Poking at this to see what next steps (if any) should be taken given the defaults change.

[RussKie]

Repo owners must remove the original flag, if it was set in their repos explicitly. Other than that I can't think of anything else.

Thanks @RussKie - @tmat, should this be reverted then in Arcade?

[tmat]

Yeah, we should revert this.
