I ran into all of this with the first few years of my career. Even after years, MAUI has struggled to gain traction and Avalonia has grown and is far more the de-facto choice for .NET cross-platform GUI. Both work collegues and myself have ran into XAML/WPF Styling horrors where it's all one giant aggregation/inheritance nightmare generated by Blend (and done by someone that didn't quite know what they were doing)
