Than you for your work ont this library about kubernetes :)

We would like to activate .NET 8 AOT on SlimFaas which is also an open source project.

[tg123]

hi @guillaume-chervet here is a draft version of aot
too many warnings and many things need to be fixed
but first working code

https://github.com/tg123/csharp/tree/aotfinal/examples/aot

dotnet publish -r win-x64 -c Debug

~20M binary

your input is welcomed, i am still working on cleaning things up

[guillaume-chervet]

Hi @tg123 thank you very much! Is it possible to publish alpha version? I need at least a working trimming mode. AOT will be the next step.

[tg123]

seems too many lib to cleanu, i am thinking add a Kubenetesclient.AOT for aot only

why do you want trim only? btw

[guillaume-chervet]

AOT will be very fine, but Trimming for à first step will be Nice. This discution is interresting dotnet/dotNext#200 (comment)

[guillaume-chervet]

Hi @tg123 are your still working on this?

I really need to activate trimming and better will be AOT for Slimfaas :
https://github.com/AxaFrance/SlimFaas

I may be will have more time if you need some help.

[tg123]

yup please allow more time on this

[guillaume-chervet]

hi @tg123 ,

Thank you s much for your work.
Is it possible to publish a beta of KubernetesClient.Aot ?
