>>If I can see a Component in .Net 5 toolbox like an ErrorProvider,
You can find the ErrorProvider under Toolbox->Components tab.
And as lextm said that the WinForms designer in .NET Core is still in its preview and currently some features are not yet supported.
I suggest you use the “Send Feedback” icon in Visual Studio top-right corner as shown in the following image and specify that it is related to the “WinForms .NET Core” area.

Well, the link is just using .Net Framework on the forms. Not really what I'm trying to accomplish.
If I can see a Component in .Net 5 toolbox like an ErrorProvider, I should be able to do it for my components. But I'm unable to do so.
This shows in the toolbox.
public partial class Component2: Component does not, or any custom component I've made
So, it is possible, but how?
