SharpDX.DXGI - DXGI_ERROR_INVALID_CALL - exception

Question

I've searched for the solution a lot, but i can't find it.
Here is my code:
namespace MySharpDXGame
{
public class Game
{
public static void Main()
{
Game game = new Game();
game.InitializeGraphics();
RenderLoop.Run(game.MainForm, game.RenderCallback);
}
private RenderForm MainForm;
private const int Width = 1280;
private const int Height = 720;
private D11.Device device;
private D11.DeviceContext context;
private SwapChain chain;
private D11.RenderTargetView rendtargview;
public Game()
{
MainForm = new RenderForm("Simple Render")
{
ClientSize = new System.Drawing.Size(Width, Height),
AllowUserResizing = true
};
}
private void RenderCallback()
{
Draw();
}
public void InitializeGraphics()
{
ModeDescription modesc = new ModeDescription(Width, Height, new Rational(60, 1), Format.R8G8B8A8_UNorm);
SwapChainDescription chaindesk = new SwapChainDescription()
{
ModeDescription = modesc,
SampleDescription = new SampleDescription(1, 0),
Usage = Usage.RenderTargetOutput,
BufferCount = 1,
OutputHandle = MainForm.Handle,
IsWindowed = true
};
D11.Device.CreateWithSwapChain(DriverType.Hardware, D11.DeviceCreationFlags.None, chaindesk, out device, out chain);
context = device.ImmediateContext;
rendtargview = new D11.RenderTargetView(device, chain.GetBackBuffer<D11.Texture2D>(0));
System.Windows.Forms.MessageBox.Show("created!");
}
private void Draw()
{
context.OutputMerger.SetRenderTargets(rendtargview);
context.ClearRenderTargetView(rendtargview, new Scolor(32, 103, 178, 255));
}
}
}
The exception is thrown at line
D11.Device.CreateWithSwapChain(DriverType.Hardware, D11.DeviceCreationFlags.None, chaindesk, out device, out chain);
I've installed DirectX SDK June 2010. My computer runs on Windows 7 SP1. I am doing this project in Visual Studio Community 2017. SharpDX libraries was downloaded from NuGet.
Here is the full log of exception:
SharpDX.SharpDXException: "HRESULT: [0x887A0001], Module: [SharpDX.DXGI], ApiCode: [DXGI_ERROR_INVALID_CALL/InvalidCall], Message: Unknown"

Try to use the Debug DeviceCreationFlags. This should help you to locate the problem. Also i can only recommend the sharpdx tutorials from robydx:
