windows phone 8 ShareMediaTask exception

Question

am trying to share an image with ShareMediaTask.

all things works except after reaching the share app my app crashes with application unhand led exception

using (Stream current = await svfile.OpenStreamForWriteAsync())
        {
            var picture = lib.SavePicture("share", current);
            ShareMediaTask task = new ShareMediaTask();


            task.FilePath = picture.GetPath();

            task.Show();

            System.Diagnostics.Debug.WriteLine("yessss");
        }

its the same with mail also after reaching selection view of mail app crashes in background .

Answer 1

//Save image to media library
//toShare is the stream source. 
//Don't use using statement to get stream

MediaLibrary library = new MediaLibrary();
var picture = library.SavePicture("Memefy_Photo", toShare);

//Open ShareMediaTask
var task = new ShareMediaTask();
task.FilePath = picture.GetPath();
task.Show();
