No, neither of these would currently work with UWP.
The primary reason is that neither Khronos API has extensions to
initialize the winsys on top of the UWP core window infrastructure. In
theory, you could initialize Dozen for offscreen rendering and then
explicitly marshal the contents out – that would probably work actually.
There’s 2 more gotchas there though:
1. The ICD loaders (OpenGL32.dll, Vulkan-1.dll) are not available in
the UWP environment. You could explicitly use the non-ICD version of
GL (i.e. Mesa’s OpenGL32.dll from the libgl-gdi target), include the
open-source Vulkan ICD loader, or use the ICD version of either
(OpenGLOn12.dll/libgallium_wgl.dll for GL – I plan to delete the
former at some point and just use the latter at some point;
vulkan_dzn.dll for VK).
2. There’s not currently extensions for D3D12 interop either spec’d or
implemented.
What do you mean by not spec'd? Vulkan and OpenGL both have standard
(KHR and EXT respectively) D3D12 interop extensions, in addition to
Vulkan<->GL, Vulkan<->D3D11-and-lower.

There’s one more problem for GL that I don’t think is problematic for
VK, which is that it uses APIs that are banned from the UWP environment,
specifically around inserting window hooks for Win32 framebuffer
lifetime management. So you’d probably have to build a custom version
that has all of that stuff stripped out to get it to be shippable in a UWP.
We (Microsoft) don’t really have plans to add this kind of stuff, at
least not in the near future, but I’d be open to accepting contributions
that enable this.

Hi, I was wandering if these two layers would work with UWP on Xbox
Series Console or if not will there be plans to add support?
