Thanks for the repor @inoyakaigor. Looks like you may be on an old store version vs. the latest code here? I think I fixed a few issues with the error alignment in the latest code. (I should have XS version # in my bug report template 😅)

I wouldn't expect the pasted in code to work for a few reasons, as the local type isn't known for your custom object, though if you have a loose DataTemplate without the DataType I'm trying to think if that'll work if you populated faux data with the data context.

Also, the x:Bind converter/processor I believe should work, but doesn't. I don't think I have a tracking issue for that. I've been working towards some new general parsing stuff first that I haven't had a chance to work on yet that may change a bit of how the rest of the systems work.

If you'd like to dig in anywhere, let me know what you need to know for me to point you in the right direction. The project is still new to being open sourced here, so good to know where any gaps in understanding of the project are. Thanks!

@michael-hawker thank you for the quick answer!
Yes it is version 1.1.0

I'm newbie at developing for Windows and wrote XAML code with LLM so I don't fully understand part about DataTemplate and DataType (I'm sorry but it is our future — people who don't have any clue what they do). How should I to do it and how? With tab "data source"?

In general I'm looking for experience like I'm used to have in a browser's devtools: when I edit preview rendered somehow even if its wrong.
