CameraPreview allows previewing the camera video stream of the WinRT MediaCapture API in Desktop WPF apps.

CameraPreview derives from D3DImage and can be used anywhere a GPU-accelerated ImageSource can be. For instance, inside an <Image> XAML element:

<Grid>
    <Image Name="Preview"/>
</Grid>

The C# code behind creates MediaCapture, initializes it, and passes it to CameraPreview. This object is then set as source of the <Image> element and preview is started.

var capture = new MediaCapture();
await capture.InitializeAsync();

var preview = new CapturePreview(capture);
Preview.Source = preview;
await preview.StartAsync();
