protected properties (not annotated) cause error

[stokara]

When adding a protected property that is not reactive to my class which partial and inherits from ReactiveObject but the class is not annotated as [Reactive ]

public partial class Class1 : ReactiveObject {
    [Reactive] public partial int ReactiveInt { get; set; }

     protected int NonReactiveInt { get; }

}

generates an error
'Class1.NonReactiveInt' is inaccessible due to its protection level

Workaround: either annotate NonReactiveInt with [IgnoreReactive] or change to public
