Microsoft web architectures of the day: Web Forms vs MVC vs Web API

I was tasked today with finding out what is the best pick to convert our desktop application into a fully web based one.

Came across the 2 following links, which I found very good, where I think most of the essential topics are covered.

• Microsoft doc's Modern Web Apps architecture
• Leonardo Esposito's reflections on Web Forms vs MVC vs Web Api

Having problems setting 2 panels in a windows form, where one is top-docked and the other fill-docked, but the fill-docked one is overflowing into the top one ?

Play with the panels "send to back" / "bring to front" (mouse right click).
