It would boost productivity if we could use generic parameters as components directly in razor pages.

Consider such container and its razor page -- MyContainer<TComponent>

<h1>This is my component</h1>
<TComponent/>

This gives error and indeed it should give error:

But if we add the constraints:

class MyContainer<TComponent> where TComponent : ComponentBase

now we know that it is truly a component, and now it would be great if Razor could recognize it as in the snippet above.

Describe the solution you'd like

See above.
