Hi Kranthi,

We have analyzed the reported issue. We have fixed the reported issue by using the following code snippet,

Code snippet 

        protected override bool OnBackButtonPressed() 

        { 

            tabView.Dispose(); 

            return base.OnBackButtonPressed(); 

        } 

Please have a modified sample for your reference,

Please check if the sample satisfies your requirement and let us know if you have any concerns.

Hi Suganya, 

thank you for your reply. 

Unfortunately, the sample you provided with the code snipped does not work. The problem still persists. I have downloaded the Sample and ran it in Debug for UWP, the issue is still the same.

Regards,

Jan Duldhardt.
