CreateSwapChainForHwnd failing with DXGI_ERROR_INVALID_CALL #431

I would like to use some of the features of the IDXGISwapChain1 interface, targeting Windows 7 and up. According to MSDN docs for IDXGIFactory2::CreateSwapChainForHwnd there are cases where Windows 7 can successfully call this function:

DXGI_SCALING_NONE is not supported on Windows 7 or Windows Server 2008 R2 with the Platform Update for Windows 7 installed and causes CreateSwapChainForHwnd to return DXGI_ERROR_INVALID_CALL when called.

I haven't been able to use this from SharpDX via the SwapChain1 constructor. It does give an Invalid Call error with any parameters I've tried. Am I doing something wrong or can this be fixed?

Example code:

var d3device = new SharpDX.Direct3D11.Device(DriverType.Hardware, SharpDX.Direct3D11.DeviceCreationFlags.BgraSupport);
var dxgiDevice = d3device.QueryInterface<SharpDX.DXGI.Device1>();
var dxgiFactory = dxgiDevice.Adapter.GetParent<SharpDX.DXGI.Factory2>();

// This works:
var oldSwapChain = new SwapChain(dxgiFactory, d3device, new SwapChainDescription
{
    BufferCount = 2,
    ModeDescription = new ModeDescription { Format = Format.B8G8R8A8_UNorm },
    IsWindowed = true,
    SampleDescription = new SampleDescription { Count = 1, Quality = 0 },
    Usage = SharpDX.DXGI.Usage.RenderTargetOutput,
    OutputHandle = handle
});

// This gives DXGI_ERROR_INVALID_CALL
var desc1 = new SwapChainDescription1
{
    Stereo = false,
    Width = 400,
    Height = 400,
    BufferCount = 2,
    SampleDescription = new SampleDescription(1, 0),
    Usage = SharpDX.DXGI.Usage.RenderTargetOutput,
    Format = Format.B8G8R8A8_UNorm,
    AlphaMode = SharpDX.DXGI.AlphaMode.Premultiplied,
    Scaling = Scaling.None,
    Flags = SwapChainFlags.None,
    SwapEffect = SwapEffect.FlipSequential
};
var newFeatureSwapChain = new SwapChain1(dxgiFactory, d3device, handle, ref desc1);

It should work (dunno about specifically this code, but accessing some API from W7 is fine) Have you correctly installed the platform update for Win7?

You're right, it should work. I have nothing to go on. The platform update came through over a year ago via Windows Update.

What gives debug output on the device? (as explained here)

When I do that, I first get:

Microsoft C++ exception: _com_error at memory location 0x0000000023BBDD20.

Then if I hit Continue, I get the SharpDXException:

HRESULT: [0x887A0001], Module: [SharpDX.DXGI], ApiCode: [DXGI_ERROR_INVALID_CALL/InvalidCall], Message: Unknown

This code is not even running on Windows 8. Have you really tried to run this on Windows 8? Also, when turning debugging on device, I get a self-explanatory message, so please, take the time to dig more into this.

I do not have access to a Windows 8 machine at work. (Personally, I prefer 8.)

I apologize for my apparent ignorance. Would you mind taking the time to explain how I can get a debug dump such as the one you have there? I have native debugging on and am creating the Direct3D11 device with the Debug flag, and that gives the _com_error above. What could I do differently?

Well, may be the debug is not working for this particular API on Windows 7. Don't have any W7 so can't confirm.
