So You Think You Know C#? Constructors
C# construction order determines which fields are ready. Field initializers, constructor chaining, virtual dispatch and static initialization explain what runs when.

Factory Pattern: The Enabler of Polymorphism
A Factory selects and constructs a concrete descendant while callers program to an interface through the base class's public contract. C# thumbnailers show selection and polymorphic dispatch.
Writing
Factory Method Pattern: The Most Beautiful Pattern We Lost
Factory Method lets consumer subclasses choose dependencies through an overridable creation hook. C# examples show its two class families and distinguish it from a separate Factory.
