[SlimDX] WPF

Hi,

[font="arial, sans-serif"]Sorry for bad English, but I have some questions about the API SlimDX.[/font]
[font="arial, sans-serif"]I wish to read obj or x files and render them in WPF.[/font]

[font="arial, sans-serif"]I first looked at the tutorials available on the official site, but they are oriented Windows Form.[/font]

[font="arial, sans-serif"]I like to use DirectX10 or 11 but I can not start, I wrote the following code:[/font]
[font="arial, sans-serif"] [/font]
[font="arial, sans-serif"]
var description = new SwapChainDescription()
{
BufferCount = 1,
Usage = Usage.BackBuffer| Usage.RenderTargetOutput,
ModeDescription = new ModeDescription((int)this.Width, (int)this.Height, new Rational(60, 1), Format.R32G32B32A32_Float),
SampleDescription = new SampleDescription(1, 0),
Flags = SwapChainFlags.AllowModeSwitch,
OutputHandle = new WindowInteropHelper(this).Handle,
IsWindowed = true,
SwapEffect = SwapEffect.Discard
};

Device device;
SwapChain swapchain;

FeatureLevel[] levels = {
FeatureLevel.Level_11_0,
FeatureLevel.Level_10_1,
FeatureLevel.Level_10_0
};

Device.CreateWithSwapChain(null, DeviceCreationFlags.Debug,levels, description, out device, out swapchain);
