An interface is a code structure that has no concrete members and similar to an abstract class. An interface can contain public members such as methods, events, properties and indexers, but these members do not provide any functionality. Instead, they define items that must be made concrete within all classes that implement this interface. This means that an interface can be used to define what a class must do, but not how it will achieve it.

Intellassist feature of CodeRush has two options pages in the Options Dialog. Both of them configure this auto-complete feature and its extensions.
Overview
The Instellassist feature of DevExpress CodeRush Pro is similar to the built-in Intellisence feature of Visual Studio. It provides additional hints that pop up as you type the code and completes the edited code with an in-scope identifier or other suggestions. These hints help you select code elements or complete the text you need in the context of what you are working on without retyping the entire text.

A constructor is a special class member that is executed when a new object is created. There are two types of constructors: instance constructors and static constructors. Instance constructors are used to create and initialize instances of classes or structures. A static constructor is used to initialize a class itself. A static constructor is called automatically to initialize the class before the first instance is created or any static members are invoked.
