Im working with a MAUI application. dotnet version 8.0
Im unable to resolve this error
Does anyone have any idea on how to resolve the below

I’m still trying to learn .Net Maui and I want to use the equivalent of a combobox. I found this on YouTube https://www.youtube.com/watch?v=gnKkUtBK23A that shows one way of making a combobox using Expander. The video was probably made for dotnet 6 and I’m using dotnet 8 so I have had to make some changes. I’m also using VS 17.10.4 on Windows 11. The basic idea is to have a list of items in an Expander. When the Expander is clicked, the list displays. Then, when an item is clicked, the item is supposed to show in the header and the list closes. This can then be repeated any number of times. My code works in so far as the item click is detected (message displays he selected item in DebugView) but the header label doesn’t update and the list remains open. I’ve checked my code but I still can’t work out why the bindings aren’t working. Here is my code:
