Everything else aside, as a frontend developer I picked up C# and XAML to build a Windows application and while I really enjoyed C# (so familiar to Typescript, funny that), I was really disapointed by XAML.
At first XAML feels really nice because you've got the nice GridView and other UI components, but the moment you want to start customising these everything falls down. I was really disapointed by it's lack of more flexible layout semantics (like flexbox or display: grid), and instead offloading that all into writing custom C# code to lay things out at pixel locations.
What was just a single line in css - grid-template-columns: repeat(auto-fit, minmax(250px, 1fr)) - ended up being many lines of custom layout code to achieve something much less performant.
I find the codegen/bindings situation to be really weird and XAML as well. Making custom XAML components/reusing code is trickier than it should be. React really got it right with JSX being just a thin layer of syntactic sugar on regular JS (I'm unsure how this would work for a static language like C#)
