           phoneCallTask.PhoneNumber = "9717098666";
           phoneCallTask.DisplayName = "Dhananjay";
           phoneCallTask.Show();
       }

Code of XAML

<Button x:Name="PhoneCall" Content="Button" HorizontalAlignment="Left" Margin="247,464,0,0" VerticalAlignment="Top" Click="PhoneCall_Click"/>

But while running an application, I encountered an error.
