now can share photo facebook using photochoosertask or cameratask. sharing experience if face same issue can use it.
private void photochoosertask_completed(object sender, photoresult e) { bitmapimage image = new bitmapimage(); image.setsource(e.chosenphoto); saveimagetoisolatedstorage(image, tempjpeg); this.image.source = image; } public void saveimagetoisolatedstorage(bitmapimage image, string filename) { using (var isolatedstorage = isolatedstoragefile.getuserstoreforapplication()) { if (isolatedstorage.fileexists(filename)) isolatedstorage.deletefile(filename); var filestream = isolatedstorage.createfile(filename); if (image != null) { var wb = new writeablebitmap(image); wb.savejpeg(filestream, wb.pixelwidth, wb.pixelheight, 0, 100); } filestream.close(); } } with can able save selected image isolatedstorage. , @ time of posting photo facebook have select image isolatedstorage.
