How Blazor Framework get notifed when the property value gets changed

Blazor automatically checks for changes of bound properties when a user interaction happened (e.g. button click, text in an input changed).

The language service is for intellisense in Visual Studio. So if you are not using Visual Studio there is no need to install it. There is no blazor intellisense support for VSCode right now or something....See ...here... for the 7.3 error.

Blazor, event listener as inline delegate or handler in @functions section

Both don't work for me with your code. But do work when I change them to ...Console.WriteLine(e.key)...I guess ...Console.Write... is not supported because browsers don't support this, ...Console.Writeline... translates to ...console.log... and ...Console.Write... has nothing to translate to.
