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

Consider such container and its razor page -- `MyContainer`

```

This is my component

```

This gives error and indeed it should give error:

But if we add the constraints:
```
class MyContainer 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
