You may want to take a look at Nevron Open Vision (https://www.nevron.com/products-open-vision.aspx). This is probably the most advanced desktop cross-platform application development framework around. I work for the company that created it and we have internally compared it to MAUI, Uno, Electron Qt etc. Nevron Open Vision is better in all aspects - it supports more controls, better integration and now also supports Blazor-WebAssembly! MyDraw is one commercial application built with it and tested by thousands of Windows and Mac users.
