TelerikWinFormsThemeName without app.config

Hi,

default behavior when creating a new WinForms project is that this setting is generated in app.config:

<appSettings>
    <add key="TelerikWinFormsThemeName" value="VisualStudio2022Light" />
  </appSettings>

Since I am using .net 6 and appsettings.json, I would love to eliminate app.config entirely.

Is there a way to move this setting to appsettings.json or implement it in code globally (without adding the code in every form or user control) and still maintain the design time functionality?

regards,
Darko
