Builder

Separates the construction of a complex object from its representation, using a fluent chain of setters that ends in Build().

Use it when: an object has many optional fields and you want to avoid a constructor with a long parameter list (or a dozen overloads).

Watch out: for a simple object with two or three fields, a plain constructor or object initializer is usually clearer than a builder.
