title: Difference between Windows App SDK and WinUI 3
body: <p>I develop many UWP apps to Windows 10, but to Windows 11 I have so many questions and sometimes the Microsoft Docs it's confusing. I want develop new apps to Windows 11 but I am totally lost!</p>
  <p>What is the difference between Windows App SDK and WinUI 3? I dont understand :(</p>
  <p>And what is the best way to develop Windows 11 apps? Still UWP? Or Windows App SDK? Or WinUI 3?</p>
  <p>UWP dont have round corners thats correct? I create a new project in my computer with Windows 11 in visual Studio 2022 and only the window of my app have rounder corners, but another elements (for example buttons) dont have rounded corners!</p>
  <p>And Mica is not only availabe in WinUI 3?</p>
