@WilliamBZA CI for linux didn't run. You need to update to ubuntu-latest.

The linux build won't work for V7 as this still has support for .NET Framework. See previous V7 release builds: https://github.com/Particular/NServiceBus.SqlServer/actions/runs/15504979270/job/43658586230.

I think we're safe to proceed without the Linux build here.

I had to fix this for Service Control last month, so I'll stick to my guns.

However, you definitely need to fix this

NServiceBus.SqlServer/.github/workflows/release.yml

Line 14 in ce33b54

runs-on: ubuntu-20.04

or the pipeline will not execute and you won't be able to release.

Please update ubuntu in the release pipeline as well:
