Writing
Give callers domain operations while collections and gateways own the details: service orchestration, model mapping and translation of recognized failures into domain exceptions.

Writing
Create instances for state or polymorphism and use inheritance for a common consumer. Static behavior and composition can keep testing from dictating every class's shape.

Writing

Writing
A Configuration Provider hides the source and returns validated, typed settings. Useful exceptions and composed settings providers keep configuration rules in one place.

Writing
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.

Quartz composes ASP.NET pages through a Builder, reusable HTML templates, and view objects. The walkthrough covers their relationships and Visual Studio templates.
