@KirillKornienko I've been able to build and run using this PR's packages using net8's Uno Platform bootstrapper, could you try with blazor net8 and let me know if it works for you?

Sure, where can I find the artifacts, attached to this PR? On https://dev.azure.com/xamarin/public/_artifacts/feed/SkiaSharp I see only -preview72 version, which isn't the latest version.

[jeromelaban]

@KirillKornienko you can find the nuget packages in the Artifacts section of the build, here. Make sure to use the versions with pr in it.
