X++ in AX7: Private and public members

Since the first version of Axapta, member variables in classes have been protected. In AX7 the default remains protected, however, you can now mark them as public or private.

Here is an example:

class MyClass
    public int PublicMember;    
    private int privateMember;    
    int protectedMember; //Defaults to protected
    protected int explicitlyProtectedMember;

You can access the public member using the same syntax as when accessing fields on Tables (or properties in C#). Notice the best practice is to use PascalCasing for public members – just like for fields on tables.

var myClass = new MyClass();
myClass.PublicMember = 42;  

There is still no support for getters and setters (like we know them from C#).
