I created a custom WinForms control. When I added reference to the control's project for any project in the same solution, the control appeared in a WinForms designer toolbox and I can use it.

But I have problem to use it as an external library. I built it and got a DLL file. When I add reference to the DLL file for a project, the control doesn't show in the toolbox. I tried also add it by "right click toolbox => choose items...", but I have an error: "'path to dll' targets a platform whose toolbox items cannot be enumerated dynamically".

I found the "answer" here: link

The only solution is workaround: Putting your controls in a NuGet package and referencing that
