.net 6 onwards, DOTNET_ is preferred over COMPlus_ dotnet/runtime@fbdcec9 it first uses DOTNET_, and then COMPlus_ as a legacy fallback.

Thanks for the updates. I’m in Europe on holiday just now so cannot review the changes properly but will do so when I’m back in Australia (3 days)

Looks like .NET 9 introduces a bunch of new required fixes. A good thing but also a chore.

[kasperk81]

.net9 work can be a separate pr from this one.

reverted, here is the history: https://github.com/SixLabors/ImageSharp/commits/522843cf11e6f965a3ad8f82304a573dd44222ff/. it fixes all CA warnings, passes all CI jobs with .net8, but fails all CI jobs with .net9 due to ONE test failure:

https://github.com/kasperk81/ImageSharp/actions/runs/11124894544 it doesn't show in github action logs had to run it locally.

@adamsitnik @eerhardt this is either .net9 regression with ReadExactly or a fix but it doesn't repro in .net8 as you can see in this github run https://github.com/kasperk81/ImageSharp/actions/runs/11124894544. unfortunately i don't have a simple repro.

[eerhardt]

@kasperk81 - can you log an issue in dotnet/runtime?
