Sandbox based on Vortice and Windows Forms

[MarcioAB]

I just created a repository named "Sandbox-Vortice-based" on my user ( https://github.com/MarcioAB/Sandbox-Vortice-based )
Can I use this name?
The idea is a sandbox to play with D3D11 and D3D12 based on Vortice and Windows Forms.
So far there are just the essential samples: direct/indexed vertices, instances, MVP transformation, and texture.
This is a work in progress and documentation is in preparation.

Hi,
Of course, keep up the good job and keep me updated!

Great!

The issue I found so far is related to dispose D3D12 objects.
I'm using Debug Layer ReportLiveObjects to check if any object is still live after I try to dispose of everything.
For D3D11 all objects are properly disposed but for D3D12 there are some objects that remain live (CommandQueue and PipelinesState).
I named all objects but this "extra" CommandQueue has no name. I guess it is created internally.
And despite the PipelineStates are named, I can not dispose them. I think they are somehow referenced by this noname CommandQueue.
This is the ReportLiveObjects after I tried to dispose all (except the device).

Any chance to suggest something I can do to dispose these objects ?

Make sure to wait idle for queue to finish pending job before releasing them, follow mine samples here: https://github.com/amerkoleci/Vortice.Windows.Samples/tree/main/src/Direct3D12

Correct. I forgot WaitForGpu() in one of many places where I dispose D3D12 objects. Thank you.
