Can we restrict the child component type in RenderFragment property

[BenLampson]

This is the Blazor component project case.
Can we restrict the child component type in RenderFragment property?

I create the container component but I can't restrict the child component type, I try to use the TagHelper but it seems not to work yet.

I want the code like this
There's a property in the container component.

[Child(CardAction)]
[Parameter]
public RenderFragment Actions { get; set; }

And I create the child item like this one:

public partial class CardAction
{
 //My code...
}

Dup of #12302. We're looking at addressing this as part of 5.0

Closing in favor of #12302. @pranavkm if you have any reason to leave this open, please say so.
