Could I add a usercontrol as toolbox item into VS2022?

Question

Hi,

I created a custom control in library with .NET Framework 4.8.

After compile it, I can add it as a item of Toolbox in VS2019. But it can not be added into VS2022.

Could anyone please help me to check it?

I attached simple user control project here:

Thanks,

Phillip Nguyen.

If you have a “Windows Forms App (.NET Framework)” project, not a “Windows Forms App”, and add the existing user control project to the solution, and start designing a form, then the user control will appear in Toolbox. You can work on main project and also improve the user control. Did you try this?
