Fully working transparent/mica/acrylic/blurred window for WinUI3.
Since the first preview of WinUi3 version 1.1 you can achieve fully transparent windows with a few Win32 API calls. And with even more Win32 APi calls you can actually achieve fully working Mica effect or Acrylic Blur or even just a normal blur.
This example project comes with a fully working TitleBar but you can create a borderless window (just like in WPF) with Helpers.Window.Presentor.SetBorderAndTitleBar(false, false);.
