UI for WPF R3 2020

What's New
NEW

Introduced the Office 2019 theme - designed to be easily modified, inspired by the well-known Microsoft Office productivity suite and its latest version. Comes with built-in Light, Gray and Dark color variations for getting off to a flying start with your WPF applications.
Implemented a new AutoSuggestBox control. It is essentially a text input control that loads dynamically a drop-down list of suggestions to choose from while the user types the text in.
Introduced new RadEntityFrameworkCoreDataSource component that provides seamless integration between an user interface and data coming from Entity Framework Core.
RadNotifyIcon is now official with the addition of custom tooltip, high DPI support, and popup close modes.
Introduced editing of TimeSpanPicker via the text box where user can now navigate, edit, delete, spin the different sections (days, hours, minutes etc.). Also, user can handle ValueEditing event in order to customize the editing process.
Slider component can be used to define multiple thumbs with which to control its values and ranges. This feature can be enabled by adding instances of the SliderThumb and RangeSliderThumb classes to its new Thumbs collection.
Introduced XLS Format Provider that handles import and export of XLS documents in SpreadProcessing library.

All Controls
CHANGED

The ScrollBarMode property and the ScrollViewerScrollBarsMode enumeration of the FluentPalette, introduced with the 2019.1.121 version of our dlls, are obsolete and replaced by the ScrollBarsMode property of the palette and the ScrollViewerScrollBarsMode enum under the Telerik.Windows.Controls.Theming namespace.

NEW

Exposed HighlightedIndex protected property to be used for keyboard navigation behavior customizations.
