I have 2020 R3 SP1 installed (2020.3.1020) and have run the toolbox configurator.
I created a new Telerik RadForm project using .NET Core. I intend this to be a .NET 5 project and have the release .NET 5 SDK installed.
After creating the project, I change it to target.NET 5.0 and compile. It compiles and runs fine.
If I then try to run the designer for RadForm1, it fails to load the designer with the message about rootcomponent value cannot be null. I also noticed that the toolbox has no Rad controls.
I tried resetting the toolbox and reapplying the toolbox configurator, but it behaves the same.
What am I doing wrong?

Hello, Paul,
The design time assemblies in .NET Core are resolved via the installed in the project NuGet packages. In order use the new designers, please make sure that the following requirements are met: https://docs.telerik.com/devtools/winforms/core/design-time#requirements
Even though you may have an installation of the Telerik UI for WinForms suite with the correct version according to the compatibility table in the referred article, it is not enough to load the designer. It requires installing the appropriate Telerik UI for WinForms NuGet package.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Thank you... that helped. However I have a problem in designing a RadRibbonForm. I can add tabs, but when I click on a tab to edit its contents, it doesn't select. Clicking anywhere on the ribbon just selects the ribbon. If I select the first tab from the drop down list, it crashes VS. If I select any of the other tabs, nothing is selected in the designer window.
I'm running version 16.8.2
Hello, Paul,
I would like to note the embedded in the designer editors are currently not available. It is one of the things that are coming next: https://docs.telerik.com/devtools/winforms/core/design-time#whats-coming-next
Hence, you should use the Visual Studio >> Properties section to edit tabs.
I have created a brand new .NET Core project and changed the Target Framework to 5.0. Even after installing the correct NuGet package, I was able to observe the Visual Studio crash. Even if using the "Edit CommandTabs" option in the smart tag, you can add tabs but when can't select the tabs at design time.
