[assembly:CLSCompliant(true)] 
namespace CLSDoc

public class Cat 
{ 
internal UInt16 _age = 0; 
private UInt16 _daysTillVacination = 0; 
//Warning CS3003 Type of 'Cat.DaysTillVacination' is not CLS-compliant 
protected UInt16 DaysTillVacination 
{ 
get { return _daysTillVacination; } 
} 
//Warning CS3003 Type of 'Cat.Age' is not CLS-compliant 
public UInt16 Age 
{ get { return _age; } } 
//valid behaviour by CLS-compliant rules 
public int IncreaseAge() 
{ 
int increasedAge = (int)_age + 1; 
return increasedAge; 
} 
} 
}
