VB.NET

VB.NET - OVERVIEW

---

Visual Basic .NET

(VB.NET) is an object-oriented computer programming language implemented on the .NET
Framework. Although it is an evolution of classic Visual Basic language, it is not backwards-compatible with VB6, and
any code written in the old version does not compile under VB.NET.
Like all other .NET languages, VB.NET has complete support for object-oriented concepts. Everything in VB.NET is
an object, including all of the primitive types (Short, Integer, Long, String, Boolean, etc.) and user defined types,
events, and even assemblies. All objects inherits from the base class Object.
VB.NET is implemented of Microsoft's .NET framework. Therefore it has full access all the libraries in the .Net
Framework. It's also possible to run VB.NET programs on Mono, the open-source alternative to .NET, not only under
Windows, but even Linux or Mac OSX.
The following reasons make VB.Net a widely used professional language:

• Modern, general purpose.
  
  
• Object oriented.
  
  
• Component oriented.
  
  
• Easy to learn.
  
  
• Structured language.
  
  
• It produces efficient programs.
  
  
• It can be compiled on a variety of computer platforms.
  
  
• Part of .Net Framework.
  
  

Strong Programming Features VB.Net

VB.Net has numerous strong programming features that make it endearing to multitude of programmers worldwide. Let us mention some of these features:

• Boolean Conditions
  
  
• Automatic Garbage Collection
  
  
• Standard Library
  
  
• Assembly Versioning
  
  
• Properties and Events
  
  
• Delegates and Events Management
  
  
• Easy to use Generics
  
  
• Indexers
  
  
• Conditional Compilation
  
  
• Simple Multithreading
  
  

VB.NET - ENVIRONMENT

Integrated Development Environment (IDE) For VB.Net Microsoft provides the following development tools for VB.Net programming:

• Visual Studio 2010 (VS)
  
  
• Visual Basic 2010 Express (VBE)
  
  
• Visual Web Developer
  
  

The last two are free. Using these tools you can write all kinds of VB.Net programs from simple command-line applications to more complex applications. Visual Basic Express and Visual Web Developer Express edition are trimmed down versions of Visual Studio and has the same look and feel. They retain most features of Visual Studio. In this tutorial, we have used Visual Basic 2010 Express and Visual Web Developer (for the web programming chapter). You can download it from here. It gets automatically installed in your machine. Please note that you need an active internet connection for installing the express edition. Writing VB.Net Programs on Linux or Mac OS
Although the.NET Framework runs on the Windows operating system, there are some alternative versions that work on
other operating systems. Mono is an open-source version of the .NET Framework, which includes a Visual Basic
compiler and runs on several operating systems, including various flavors of Linux and Mac OS. The most recent
version is VB 2012.
The stated purpose of Mono is not only to be able to run Microsoft .NET applications cross-platform, but also to bring
better development tools to Linux developers. Mono can be run on many operating systems including Android, BSD,
iOS, Linux, OS X, Windows, Solaris and UNIX.
