Core C# Programming Constructs

class Employee { // Field Data // Constructors // Methods // Properties }

Using partial classes, you could choose to move the constructors and field data into a brand new file
named Employee.Internal.cs (please note, the name of the file is irrelevant; here I just tacked on the
work internal to represent the guts of the class).

// Employee.cs partial class Employee { // Methods // Properties } // Employee.Internal.cs partial class Employee { // Field data // Constructors }
