Failed to create IDirect3DDevice

[silentlie]

Hi there,

I'm creating a simple IDirect3DDevice so I can pass input Direct3D11CaptureFramePool.Create, then get frames of a specific window.

But I keep getting this error: Failed to create a CCW for object of type 'System.__ComObject' for interface with IID 'A37624AB-8D5F-4650-9D3E-9EAE3D9BC670': the specified cast is not valid.

using var d3d11Device = D3D11.D3D11CreateDevice(
    DriverType.Hardware,
    DeviceCreationFlags.BgraSupport | DeviceCreationFlags.VideoSupport
    
);
using var dxgiDevice = d3d11Device.QueryInterface<IDXGIDevice>();
var hr = CreateDirect3D11DeviceFromDXGIDevice(d3d11Device.NativePointer, out var pUnknown);

if (hr != 0)
    throw new Exception($"CreateDirect3D11DeviceFromDXGIDevice failed. HRESULT: {hr:X}");

var device = Marshal.GetObjectForIUnknown(pUnknown) as IDirect3DDevice;
Marshal.Release(pUnknown);

return device!;
