A reference type can have an actual value of null, meaning it has no value. A value type can’t have a value of null. For example, how would you express that some boolean value is true, false, or unknown? Regular Boolean can be only true or false.
XAML Islands enable .NET and native Win32 applications to host UWP XAML controls. You can enhance the experience and functionality of your existing desktop applications with the latest UI innovations previously only available for UWP apps. For example, you can use the UWP XAML controls such as ColorPicker, InkCanvas, CalendarView, and NavigationView in your existing C++ Win32, Windows Forms, and WPF applications.

The .NET Framework contains all the classes you need to use the main cryptographic algorithms. Most of the algorithms require configuration. Be sure to check the documentation to know what are the recommended values.

A good product requires good user interaction. Products that are using search boxes will be expected to have auto-completion/suggestion feature. In WPF platform, the default text box control does not have any built-in auto-completion/suggestion feature. There are many 3rd party libraries out there which provide auto-complete/suggestion text box control as a replacement to the default WPF text box control. Most of these libraries are available in the paid version and those which are available for free, are difficult to get integrated with your existing code. So, I have created a very simple AutoComplete/Suggestion control for WPF platform without using any external library.
