   [SlimDX] - June 2010 - Direct2D.RenderTarget.FromDXGI fails
  Hi there,I am trying to get the DXGI RenderTarget working with Direct2D but I am getting the following exception when creating rendertarget with SWAP chain. I am using SlimDX JUNE 2010 release."E_INVALIDARG: An invalid parameter was passed to the returning function (-2147024809)"Any help appreciated.Here is the sample code. var desc = new SwapChainDescription()  { BufferCount = 1, ModeDescription = new ModeDescription(this.ClientSize.Width, this.ClientSize.Height, new Rational(60, 1), Format.R8G8B8A8_UNorm), IsWindowed = true, OutputHandle = this.Handle, SampleDescription = new SampleDescription(1, 0), SwapEffect = SwapEffect.Discard, Usage = Usage.RenderTargetOutput  };  SlimDX.Direct3D10.Device device;  SwapChain swapChain;  SlimDX.Direct3D10.Device.CreateWithSwapChain(null, SlimDX.Direct3D10.DriverType.Hardware, SlimDX.Direct3D10.DeviceCreationFlags.Debug, desc, out device, out swapChain);    SlimDX.DXGI.Surface surface = Surface.FromSwapChain(swapChain, 0);  RenderTargetProperties rp = new RenderTargetProperties()    {   HorizontalDpi = 96,    VerticalDpi = 96,    MinimumFeatureLevel = FeatureLevel.Default,    PixelFormat = new PixelFormat() {AlphaMode = AlphaMode.Premultiplied, Format = SlimDX.DXGI.Format.Unknown},    Type = RenderTargetType.Default,    Usage = RenderTargetUsage.None    };    //The following line works.  SlimDX.Direct3D10.Texture2D backBuffer = SlimDX.Direct3D10.Texture2D.FromSwapChain<SlimDX.Direct3D10.Texture2D>(swapChain, 0);  SlimDX.Direct2D.Factory factory = new Factory(FactoryType.SingleThreaded, DebugLevel.Information);  //This following line fails.  RenderTarget target = RenderTarget.FromDXGI(factory, surface, rp);
  You need to create a D3D10.1 device with the DeviceCreationFlags.BgraSupport flag set in order to interact with D2D. For example:SlimDX.Direct3D10_1.Device1 device;SwapChain swapChain;SlimDX.Direct3D10_1.Device1.CreateWithSwapChain(null, DriverType.Hardware, DeviceCreationFlags.BgraSupport,   SlimDX.Direct3D10_1.FeatureLevel.Level_10_0, desc, out device, out swapChain);;  Great! Thanks.This works.
