I've created .Net 5 project , however telerik controls can't be seen on xaml designer, although wpf default controls are shown well. On running, all controls are seen and working without problem.
With the help of many threads regarding this subject , I found your reply how to remove designer cache and set the extension option,etc. While I did all steps as you said, no success yet.
My situation is as follows,
- telerik 2021.2.615 and vs2019 16.10.2 installed.
- projects are created as WPF 5.0 project, not by tererik wpf template because it only support till .net 4.5.
Projects target is 'ANY CPU'.
- NoXaml dlls are copied to solution folder from installed directory, and all projects referenced those.
Double checked that no cross referenced dll exists between NoXaml and Xaml dlls.
During checking, I found that toolbox configuratIon supports only .net 4.5. as attached image.
Does that mean that I missed something ? so designer failed to load telerik controls ?
