C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

CSLA .NET was expounded in Expert C# Business Objects [3] and Expert One-on-One Visual Basic .NET Business ObjectsISBN 1-59059-145-3, both written by Lhotka. Although CSLA and CSLA .NET were originally targeted toward Microsoft programming languages, most of the framework can be applied to most object oriented languages.
The system can be designed visually with the Unified Modeling Language (UML). Each component is shown as a rectangle, and an interface is shown as a lollipop to indicate a provided interface and as a socket to indicate consumption of an interface. Component-based usability testing is for components that interact with the end user.
Object-oriented languages extend the notion of type to incorporate data abstraction, highlighting the significance of restricting access to internal data through methods. [48] Eric S. Raymond has written that object-oriented programming languages tend to encourage thickly layered programs that destroy transparency. [49]
This is a common approach shared by the Java programming language, Smalltalk, C# and many other object-oriented programming languages. VCL components cover Windows controls like windows (TForm class), controls (e.g., TButton, TCheckBox, TLabel classes) as well as database access (e.g., ADO or IBX components) or Internet connections (Indy ...

Design by contract (DbC), also known as contract programming, programming by contract and design-by-contract programming, is an approach for designing software. It prescribes that software designers should define formal , precise and verifiable interface specifications for software components , which extend the ordinary definition of abstract ...
