@guardrex There is still one more instance of the Culture property in the Dynamically set the server-side culture by user preference section where the logic resides in the property's getter and setter (a practice neither I nor the documentation and code analyzers recommend). However, the setter does not invoke async JS interop.

Please let me know if I should also update this demo to use @bind:after (either in this PR or a separate one).

UPDATE: The documentation and code analysis are explicitly violated when the property used as a [Parameter] is not an auto-property. However, this is not the case here. Nevertheless, I believe that binding to properties that contain logic is inappropriate and should only be used in advanced scenarios.

Yes, please feel free to address that on this PR. Fortunately, the version flipping in and out of 8.0 won't affect your update 😅.

Super-tiny-👶-NIT ... I'm going to place a blank line prior to the if lines. That's just to match our convention for if-blocks following other lines of code. UPDATE: Done! 👍

Fantastic set of updates ... again! Is there any such thing as Blazor MVP of the Year? There should be! I'll mention this one to Dan and Artak this Friday.

WRT the culture storage approach (local storage or loc cookie) for BWA apps, Mackinnon will be along in July/August to break the tie. He's going to decide which approach the article will take. Of course, I bet on Hisham because I'm I silly green hack-o-saurus 🦖, and Hisham is like you ... a REAL programmer! 😆

While I appreciate the praise as much as anyone, there's no need to overdo it. I'm just doing what I enjoy. ;-)
