Change Log

Below, you can see what was changed in each version of Remote Core .NET Viewer SDK. 

This document does not list every small improvement, it includes only the most important changes. For more details, see the Documentation folder.


Mar 15, 2022 — .NET Viewer v2022.1.1

Common:

  • Core component: .NET 5.0 and .NET 6.0 are supported. 
  • WPF & WinForms: .NET 5.0-windows and .NET 6.0-windows are supported.

New features:

  • Add the WPF FileTransferControl to easily implement file transfer functionality into a WPF application. The control has a default style and may be overridden using WPF RemoteDesktopControl as well. See details in the Example solution (WPF Demo project).
  • Add the File transfer capabilities to the WPF RemoteDesktopControl (Add the properties to get the low-level file transfer core component that may be used to set up file transfer functionality).
  • IViewerCore.RegisteredExtensions property returns a list of registered extensions.
  • Add ILogSource interface to logging Core extensions (File transfer in particular).

Breaking changes:

  • For WPF RemoteDesktopControl template overriding: the named part PART_InputEventsListener of type UIElement is required in Connected state now. It goes in place of PART_RemoteDesktopImage, so the last one is not a necessary part of the template any more.
  • IViewerCoreExtension interface gets a new member: CheckStatus method which is called when all capabilities from remote Host are received and you may check if needed ones are available if it is necessary.
  • TargetFileExist Event in FileTransferCore marked as Obsolete with the compiler error generation. Use ResolveFilesConflict callback instead.
