Just realized there is an extra logging change in the backport. Is that expected? |

when is this expected to be released? is there a way I can download the staging/beta version of the runtime in the mean time? |

Hi @danny-zegel-zocdoc, this fix should be in .NET 9 preview 6. You can download that here: https://dotnet.microsoft.com/en-us/download/dotnet/9.0 |
i'm working in .NET 8, would like a .NET 8 runtime |

The next .NET 8 update will be later this month. |
