directx9-directx11 shared texture creation fails SharpDX

Question

i have an wpf app and trying to switch from rendering onto winforms control to rendering onto image using d3dimage (cause i want to be able to place some wpf interface on top of rendering image, airspace problem and all that), so i know i need to create directx 9 device and create shared texture, i'm trying to follow other people's examples, but for some reason shared texture creation fails (but not just directx 9 texture, only when i pass handle of directx 11 texture to it's constructor), i tried using both hardware and reference devices for either directx 9 or directx 11, i tried to tweak formats, creation flags, nothing helped, followed all restrictions described here https://learn.microsoft.com/ru-ru/windows/win32/api/d3d11/nf-d3d11-id3d11device-opensharedresource?redirectedfrom=MSDN and still no result, any ideas? xaml:

Creating DirectX9 3D device as Direct3DEx and DirectX9 device as Device (without Ex) and using hardware device type in both DirectX9 and DirectX11 devices solved the problem, no other combination worked, here is the working code in my case:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    var device = new SharpDX.Direct3D11.Device(DriverType.Hardware, 
        DeviceCreationFlags.Debug | DeviceCreationFlags.BgraSupport, 
        FeatureLevel.Level_11_0);

    var texture = new SharpDX.Direct3D11.Texture2D(device, 
                  new Texture2DDescription()
    {
        Width = WinFormsControl.ClientSize.Width,
        Height = WinFormsControl.ClientSize.Height,
        ArraySize = 1,
        BindFlags = BindFlags.RenderTarget | BindFlags.ShaderResource,
        Usage = ResourceUsage.Default,
        CpuAccessFlags = CpuAccessFlags.None,
        Format = SharpDX.DXGI.Format.B8G8R8A8_UNorm,
        MipLevels = 1,
        OptionFlags = ResourceOptionFlags.Shared,
        SampleDescription = new SampleDescription(1, 0)
    });
    
    var d9context = new SharpDX.Direct3D9.Direct3DEx();
    
    var d9device = new SharpDX.Direct3D9.Device(d9context, 0, 
                   DeviceType.Hardware, IntPtr.Zero, 
                   CreateFlags.HardwareVertexProcessing, 
                   new SharpDX.Direct3D9.PresentParameters()
    {
        Windowed = true,
        SwapEffect = SharpDX.Direct3D9.SwapEffect.Discard,
        DeviceWindowHandle = WinFormsControl.Handle,
        PresentationInterval = PresentInterval.Default,
    });
    
    var handle = texture.QueryInterface<SharpDX.DXGI.Resource>().SharedHandle;
    var d9texture = new SharpDX.Direct3D9.Texture(d9device, 
                    texture.Description.Width, texture.Description.Height, 1, 
                    SharpDX.Direct3D9.Usage.RenderTarget, 
                    SharpDX.Direct3D9.Format.A8R8G8B8, Pool.Default, 
                    ref handle);
}

Does your D3D9 texture update correctly after a render cycle? Mine, using the same initialization code as you + using the var surface = d9texture.GetSurfaceLevel(0) to set the backbuffer to the D3DImage only displays the update to the screen after a second or third render.

Nicke Manarin Feb 4 at 13:51

Oh, If a shared texture is updated on one device ID3D11DeviceContext::Flush must be called on that device., That was it, I just had to call _d3d11Device.ImmediateContext.Flush(); after the render cycle.

Hmm, but that's not it. It started updating the image more frequently, but still most of the time the new rendered content is not being displayed (old frame content still is displayed). PresentInterval.One did not help.
