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.

Windows Forms App (.NET Framework) is different from Windows Forms App, so you need to pay attention when using it.
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?
Thank you!
I tested with different type of projects
