Visual Basic .NET (VB.NET) - VB.Net is a Microsoft object-oriented programming (OOP) language. It evolved from Visual Basic 6 (VB6) to meet an increasing need for easy Desktop Application, web-services and web development.
VB.Net was designed to take advantage of the .NET framework-based classes and run-time environment. It was re-engineered by Microsoft as part of its .NET product group.VB.NET supports abstraction, inheritance, and polymorphism.The most substantial VB6 to VB.NET modification is OOP, which allows for class and object creation and increased code reusability. Many new controls were added to streamline program development. VB.NET also supports multithreading andWeb development services, such as Web forms and services. VB.NET’s data handling is represented and exchanged via XML-based ADO.NET, which allows for efficient and easy handling of large amounts of data via the Web.
C# (pronounced "C-sharp") - C# is an object-oriented programming language from Microsoft that aims to combine the computing power of C++ with the programming ease of Visual Basic. C# is based on C++ and contains features similar to those of Java.
C# is designed to work with Microsoft's .Net platform. Microsoft's aim is to facilitate the exchange of information and services over the Web, and to enable developers to build highly portable applications. C# simplifies programming through its use of Extensible Markup Language (XML) and Simple Object Access Protocol (SOAP) which allow access to a programming object or method without requiring the programmer to write additional code for each step. Because programmers can build on existing code, rather than repeatedly duplicating it, C# is expected to make it faster and less expensive to get new products and services to market.
