in C#. Bridge is a structural design pattern that divides business logic or huge class into separate class hierarchies that can be developed independently. One of these hierarchies (often called the Abstraction) will get a reference to an object of the second hierarchy (Implementation). The abstraction will be able to delegate some (sometimes ...Why Refactor. Often fields are moved as part of the Extract Class technique. Deciding which class to leave the field in can be tough. Here is our rule of thumb: put a field in the same place as the methods that use it (or else where most of these methods are). This rule will help in other cases when a field is simply located in the wrong place.
