On lesson 2 I'm getting the error message:
Error 1 The type or namespace name 'Device' could not be found (are you missing a using directive or an assembly reference?)

On the line:
private Device device;

My references are:
Microsoft.DirectX;
runtime ver - 1.1.4322
ver - 1.0.2902.0

Microsoft.DirectX.Direct3D;
runtime ver - 1.1.4322
ver - 1.0.2911.0

I have the lines:
using Microsoft.Samples.DirectX.UtilityToolkit;
using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;
using Microsoft;

What am I doing wrong?
