示例1: Go

                scenarioData.AddDataToScenarioRunner(runner);

                // Create the image source and the render target.  These sizes are hardcoded and independent of the 
                // display's DPI since we just want a small image to convince ourselves that the scenarios really are 
                // rendering the right thing.
                Image = new CanvasImageSource(device, 128, 128, 96);

                using (var rt = new CanvasRenderTarget(device, 128, 128, 96))
                {
                    // We actually run the scenario on the thread pool - XAML really falls down if you overload the UI thread.
                    var time = await Task.Run(() =>
                    {
                        // Run the scenario multiple times to try and avoid too much noise

                            // Hold the device lock while we run the scenario - this prevents other threads
                            // from interacting with the device and interfering with our recorded time.
