Errors when capturing component references in nullable context

[marinasundstrom]

I have a Blazor app in which I want to capture a reference to a component in code:

       <Counter @ref="counter" />

In a variable like this:

    Counter? counter;

This should work but the generated Razor component code does not handle nullable correctly. It performs a cast to a non-nullable.

Error CS8600: Converting null literal or possible null value to non-nullable type. (CS8600)

Can I avoid this error?
