Control products now ship in both Microsoft .NET Framework 4.0 and Microsoft .NET Core 3.0 assembly variations. You will now be able to use native .NET Core-based Actipro assemblies in your .NET Core apps.
NuGet Packages
Another big request has been to supply NuGet packages for the controls. NuGet packages are published on nuget.org and contain both the .NET Core and .NET Framework variations of the assemblies.
Ribbon
Made massive updates to modernize the Ribbon and all of its controls so that it renders similar to the latest Microsoft Office version.
Added subtle animations for things like Ribbon selected tab underlines, and animating the selected tab's content into view.
Updated Backstage in modern themes to use WindowChrome's new overlay feature, and to animate into place.
Updated Ribbon to use its inherited font size, allowing it to keep a consistent appearance with the rest of the containing Window.
Updated ButtonBase.Command property changes to not immediately coerce the CommandParameter property.
Removed the Ribbon.UseScenicLayout property since the old Microsoft Office 2007 orb application button style is no longer supported.
