change EnableNotifyError field to property

[zerodev1200]

I have created a library called R3Utility.
In this library, I have defined the following method:

public static Observable<bool> CreateCanExecuteSource(bool forceInitialNotification = true, params IBindableReactiveProperty[] properties)
{
    if (properties == null || properties.Length == 0)
    {
        throw new ArgumentNullException(nameof(properties));
    }
    // Create observables for HasErrors of each property
    var errorObservables = properties
                            .Select(prop =>
                            {
                                if (forceInitialNotification)
                                {
                                    prop.OnNext(prop.Value); // Force initial notification
                                }
                                return Observable.EveryValueChanged(prop, x => x.HasErrors);
                            });
    return errorObservables.CombineLatestValuesAreAllFalse();
}

By changing EnableNotifyError to a property, I can now perform the following validation:

if (!prop.EnableNotifyError)
{
    throw new ArgumentException($"Property must have EnableValidation() called.");
}

I placed bool EnableNotifyError { get; } in the non-generic interface rather than the generic one to ensure it can be accessed regardless of the type in the above method.

Please review this implementation.
