Nullability of reference types in type of parameter 'name' of 'TOptions TestOptionsMonitor<TOptions>.Get(string name)' doesn't match implicitly implemented member 'TOptions IOptionsMonitor<TOptions>.Get(string? name)' (possibly because of nullability attributes).

Non-nullable field 'currentListener' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable property 'CurrentValue' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
