Refer dotnet/sdk#38857

[PaulusParssinen]

Will all the issues be transferred over by maintainters or do we need to copy them over?

[aetos382]

please archive this repository.

[Frulfump]

please archive this repository.

I suspect that will happen after .NET 8 and 9 goes out of support in November and after maybe a little grace period.

But please move all issues that are still relevant to the dotnet/sdk repo. And maybe start some agents that try to fix the issues as well :P
