Thanks @Abdo-reda. I've removed the "zone pivots" at the top of this article. The AllowOutOfOrderMetadataProperties property is available on down-level versions, including .NET 8, via a NuGet package, so I think this article is fine as-is.

@gewarren i'm sorry but i don't understand how to actually use AllowOutOfOrderMetadataProperties in the current version of net8 and net9.

From the current documentation, it would seems that we should be able to add this simple property in the JsonSerializerOptions but i cannot find it anywhere....

Could you be more explicit and explaining how i can do this.
Thanks a lot !
