I have a problem, textbox when using the TouchEnter incident to report the error, as shown in the figure, please ask how to solve.

ArgumentException: Can only use ActionExtension with a Command property or an event handler

I spent all morning trying to figure out why this is happening, and it's caused by something deep in the bowels of WPF that I can't get to. I'll check whether this works in .NET Core, but I'm afraid this is probably something I can't fix.

No thanks, I managed to reproduce it. It seems to be something to those Touch events: IProvideValueTarget.TargetProperty is null, which means I don't know what type of object to return.
