#699 – Types Are Implicitly Internal

When you define a type in C#, you can define its accessibility as either public or internal.  Public types are visible to all code.  Internal types are visible only to code within the same assembly.

By default, if you don’t include an access modifier when defining a type, the type’s accessibility will be internal.

In the example below, the Dog class will be visible only to code within the same assembly.

    // No access modifier => type is internal, visible
    //   only to code within the same assembly.
    class Dog
    {
        // Public properties
        public string Name { get; set; }
        public int Age { get; set; }

        // Instance constructor
        public Dog(string name, int age)
        {
            Name = name;
            Age = age;
        }

        public void Bark()
        {
            Console.WriteLine("Woof");
        }
    }
