No Support for WinUI 3 UWP Going Forward

Microsoft’s WinUI 3 framework supports both Desktop (Win32) and UWP apps. Based on feedback we received from our users, we’ve learned that the majority of our customers are interested in working with WinUI 3 for Desktop (Win32). Microsoft has also prioritized WinUI 3 for Desktop in their roadmap. As such, we decided to drop the support for WinUI 3 UWP. We will now fully invest our energies on WinUI 3 for Desktop.

  • Added Windows App SDK 0.8 (formerly known as Project Reunion 0.8) support


  • WinUI 3 Desktop (Win32) app support
  • DevExpress WinUI Project Template for Visual Studio

What is the relationship (if any) of WinUI to WPF? I can't see abandoning a very deep investment in WPF for yet another UI framework from MS - will it still be here in 5 years? Or is it truly the last UI framework for Windows?

Although they have similarities, WinUI and WPF are completely different platforms. Unlike WPF, WinUI is in an early stage of development. We believe it has potential, but only time will tell if the marketplace deems it a success. To your question – It’s difficult to know whether WinUI is Microsoft’s final UI Framework for Windows.

As for WPF, it is a stable and mature desktop development platform, and it is going to be supported for a long time. We will continue to support and deliver updates to our WPF product line in the foreseeable future.

Great work neverthless 🙂

Thanks for the feedback. I repeated your steps on a couple of machines, but couldn't reproduce the exception. Experience tells me that this might be something related to the WinUI core (still in active development) as exceptions do occur under specific conditions. I created a public bug report so that we can try to reproduce the issue and research it further:

I looked at the demo, I'm impressed with what is there so far. For assorted reasons I am liking this a lot more than the UWP controls. It makes sense also that you're going with win32 only, I think UWP just couldn't catch a break because it didn't supply a significant enough of an improvement over WPF and the debugging experience was painful. It's a shame, but this isn't the first and won't be the last time Microsoft (or anyone for that matter) made a product that couldn't gain traction.

Regarding these new WinUi controls - I presume these will NOT work with MAUI out of the box, correct? It seems that WinUI controls should work with MAUI based on what I am reading here -

I appreciate your feedback, Stephen.

As for MAUI, DevExpress WinUI controls (or any other WinUI controls) will NOT work there. The idea of Single Project Templates is that you can develop a project with MAUI components and deploy it as a WinUI app. MAUI components will use WinUI APIs internally in this case, but you will work with MAUI components and APIs in your code.

If you are interested in our plans for MAUI components, check this blog post:
