Container images for .NET 9 Preview 3 are now available. See the .NET 9 Preview release notes for a summary of what's new.

Note

Alpine ARM32 images are now available again with 9.0 Preview 4. See the comment below.

Due to an issue in the .NET SDK , Alpine 3.19 ARM32 images with 9.0 Preview 3 will not be published.
We are working to have these images re-published in future previews.
You can follow the GitHub issue to see our progress.
Other ARM32 images are unaffected.
