Specificity: C#, Avalonia.
Status: discarded.
Reason: multiple problems with UI elements (no editable ComboBox, spacing for grid cells, options for disable minimize/resize buttons in dialogs, masked text box, an obscure and complex way to implement graphics drawing components using pure framework means without diving into specific platform-specific renders). Fully covered by the functionality of Eto.Forms in the absence of the same problems.
