Strange if i change

private void OnImageTapped(object obj)
{
var photo = obj as Photo;
var bphotos = new BPhotos
{
Name = photo.Media_url.ToString(),
Koala = photo.Permalink.ToString()

};
var PhotoDetail = new PhotoDetail();
PhotoDetail.BindingContext = bphotos;
App.Current.MainPage.Navigation.PushAsync(PhotoDetail);
}

to 

private void OnImageTapped(object obj)
{
var photo = obj as Photo;
var bphotos = new BPhotos
{
Name = photo.Media_url.ToString(),
Koala = photo.Permalink.ToString()

};
var PhotoDetail = new PhotoDetail(bphotos.Name,bphotos.Koala);
PhotoDetail.BindingContext = bphotos;
App.Current.MainPage.Navigation.PushAsync(PhotoDetail);
}

It work in release mode too but... I don't know why there is this difference

Hi Milka, 
 
We have checked the reported scenario from our side. We would like to inform you that the PhotoDetail’s parameterized constructor may set the data for the properties which resolved the reported scenario. Please let us know if you need further assistance.
