Get Jpeg properties from Image in Windows Phone 8.1

I need to get Jpeg properties from a image taken from the image library in the phone. In another XAML project I could use 

var myImage = System.Drawing.Image.FromStream(myImageStream);
foreach(var imageProperty in myImage.PropertyItems)
     //do things

How should I do in Windows Phone 8.1? I need property with Id 274 (Orientation) to be able to rotate the image to correct orientation

First be sure to allow access to the Pictures Library in your application manifest.

Then this code should work:

// First get the list of all your pictures in the pictures library
var allMyPictures = await KnownFolders.PicturesLibrary.GetFilesAsync();
// iterate trough your pictures
foreach (var file in allMyPictures)
{
    // Get all the properties
    var properties = await file.Properties.GetImagePropertiesAsync();
    // Get the orientation
    var orientation = properties.Orientation;
}

Be aware that pictures taken from the phone camera are not directly saved in the pictures library but in a subfolder ("Camera Roll" on my Nokia). If it's the case on yours you need to adapt like that:

// Get the Camera Roll subfolder
var cameraRollFolder = await KnownFolders.PicturesLibrary.GetFolderAsync("Camera Roll");
// Get all the pictures from this specific directory
var allMyPicturesFromCameraRoll = await cameraRollFolder.GetFilesAsync();

This code was tested on my Nokia 635 but should work on any Windows Phone 8
