DOT NET INTRODUCTION

    DOT NET

The .NET Framework is a development and execution environment that allows different programming languages and libraries to work together seamlessly to create Windows-based applications that are easier to build, manage, deploy, and integrate with other networked systems. Built on Web service standards, .NET enables both new and existing personal and business applications to connect with software and services across platforms, applications, and programming languages. These connections give users access to key information, whenever and wherever you need it.

Microsoft .NET connected software makes the "real-time" enterprise real by enabling information to flow freely throughout the organization, accessible to business partners, and delivering value to customers. With .NET-connected software, users can increase the value of existing systems and seamlessly extend those systems to partners, suppliers, and customers.

• Connected.

• Compelling

• Ubiquitous and Productive

      Connected

DOT NET Framework empowers developers to build applications that require robust messaging systems or flexible workflows.

     Compelling

With the .NET Framework, developers and designers can collaborate to create rich user experiences.

      Ubiquitous and Productive

The .NET Framework, including improvements like LINQ, provides a single platform to quickly build mobile desktop and server-based applications.

      Visual Basic .NET (VB.NET) overview:

The Visual Basic .NET programming language has a syntax that is similar to English, which promotes the clarity and readability of Visual Basic .NET code. Wherever possible, meaningful words or phrases are used instead of abbreviations, acronyms, or special characters. Extraneous or unneeded syntax is generally allowed but not required.

The Visual Basic .NET programming language can be either a strongly typed or a loosely typed language. Loose typing defers much of the burden of type checking until a program is already running. This includes not only type checking of conversions but also of method calls, meaning that the binding of a method call can be deferred until run-time. This is useful when building prototypes or other programs in which speed of development is more important than execution speed. The Visual Basic .NET programming language also provides strongly typed semantics that performs all type checking at compile-time and disallows run-time binding of method calls.

This guarantees maximum performance and helps ensure that type conversions are correct. This is useful when building production applications in which speed of execution and execution correctness is important. Visual Basic .NET is an object-oriented computer programming language that can be viewed as an evolution of the classic Visual Basic (VB), implemented on the .NET Framework. Microsoft currently supplies two main editions of IDEs for developing in Visual Basic: Microsoft Visual Studio 2012, which is commercial software and Visual Basic Express Edition 2012, which is free of charge. The command-line compiler, VBC.EXE, is installed as part of the freeware .NET Framework SDK. Mono also includes a command-line VB.NET compiler.
