Following verbatim the Visual Studio tutorial
I created the test DemoCalculator Custom Control Project class library. I then create the DemoCalculatorTest forms application.
1) When I Add>Reference, the Reference the Custom Control project does not show up. I manually browse and add the dll, but am unable to add it to the toolbox to use it in designer mode. I've tried difference things, like manually adding click on the control in the Reference dialog, manually adding the control to the toolbox using Choose Items, but nothing works.
Is it possible to create a custom control and use it in designer mode at all?
I am using Visual Studio 2022 V 17.3.6, .NET Framework Version 4.8.04084
