I am using VS 2019.
I have a custom control dll that I created. It contains a number of customized controls. It also contains a few customized forms.
I can select the dll to add to the VS toolbox. Only the controls appear in the listing, not the forms.

Is there any way to make the custom forms available?

I have searched on the internet for a solution to this and did not find anything.

YOu can't add a Form to the toolbox, because it contains items that can be added by drag and drop to a Form at design time - and you can't drop a form on a form, that doesn't make any sense as it can' be "enclosed" in the form itself! Instead, a form is created and displayed at runtime - so it needs to be added via the code, not the designer.

However, you can drag and drop code fragments to the toolbox from the code window, and drag'n'drop them into other code as "boilerplate" code: just highlight the code to create and display your form, then drag'n'drop it onto the Toolbox. You can then drag it back onto your code at any time.
