Lacking documentation on 9on12 Interop API about d3d12translationlayer

That all looks right, except you have to CreateDevice() before the QueryInterface will work. I don't think those exports are in d3d9.lib and we should probably fix that.

Thank you for your quick reply @jenatali. I missed that I had to call QueryInterface on the device... It's working now.

...
    hr = m_pD3D->CreateDevice(AdapterToUse, pDeviceInfo->DeviceType, m_hWndFocus, pModeInfo->dwBehavior | D3DCREATE_MULTITHREADED, &m_d3dpp, &m_pd3dDevice);

    if( SUCCEEDED(hr) )
    {

        IDirect3DDevice9On12* mpD3D12 = NULL;
        hr = m_pd3dDevice->QueryInterface(__uuidof(IDirect3DDevice9On12), (void**)&mpD3D12);
...

edit:
I will close this issue and reference another one regarding the d3d9.lib issue.
