await PhotoTask.IsWindows10();

This photo task has a simple constructor, which require only the destination file where to write the cropped image, for example

var destFile = await ApplicationData.Current.LocalFolder.CreateFileAsync("test.jpg");

var task = new PhotoTask(destFile);

//Select cropped width
task.CropWidthPixels = 400; 

//Select cropped height
task.CropHeightPixels = 400; 

//Choose if you want to show an elliptical crop guide
task.EllipticalCrop = true; 

//Choose if you want to enable the option to take a photo as image to pick
