Hi Asad Yes that's correct. Lets say if you are about to use traditional CLR proeprties then I'm sure you are about to miss the ease of binding. Only dependency properties can do that in both xaml and code-behind level. Where as you have to assign the CLR property's value where ever necessary to be updated in your app. Then your code-behind looks like a WinForms framework rather utilizing the concepts in WPF and UWP. Hope your ideas got narrow. Regards Amresh S.
