What's New in Visual Basic and Visual C#

Visual Studio .NET 2003

Visual Basic and C# both have RAD (rapid-application development) support in Visual Studio .NET, with project templates, designers, and other features of the development environment. Both languages use the .NET Framework base classes.

In This Section

What's New in Web Development
Visual Basic and C# include support for Web Forms and XML Web services. Web Forms allow you to easily and quickly create the browser-based interface for ASP.NET Web applications. XML Web services allow you to package a Visual Basic or C# method and make it accessible on the Web.
What's New in Data
ADO.NET provides scalable, high-performance data access for all Visual Studio applications based on the .NET Framework. You can access data directly in the data source or create an in-memory cache — a dataset — for working with disconnected data. You can also work directly with XML as relational data or by creating and editing XML files directly.
What's New in Windows Forms and Controls
You can use Windows Forms and controls to create the presentation layer of a distributed application. Windows Forms provides a clear, object-oriented, extensible set of classes that enable you to develop rich Windows applications.
What's New in Projects
You can use the Project templates in this version to easily create various types of Windows and ASP.NET Web applications and controls. Project templates set necessary references for you, import namespaces, and add default items to your projects.
What's New in Components and Component Authoring
You can use nonvisual components and associated features to incorporate resources such as message queues, event logs, and performance counters into your applications. This version also offers RAD support for component creation via the Component Designer and framework classes that help you create controls and components.
What's New in Debugging
You can now debug projects that are part of the same solution but written in different languages, perform remote debugging, and implement trace functionality throughout your code to retrieve finely tuned output.
What's New in Extensibility and Automation
Visual Studio .NET includes a programmable object model that provides access to the underlying components and events of the integrated development environment (IDE). This model allows you to extend the functionality of the IDE, automate repetitive tasks, and integrate the IDE with other applications.
What's New in International Applications
Internationalization features in Visual Basic .NET make it easy to create applications targeting multiple locales, building on the globalization and localization features of the .NET Framework.
What's New in Upgrading
Visual Basic .NET 2003 now includes support for upgrading Visual Basic 6.0 WebClass and UserControl projects, plus a new tool for upgrading blocks of Visual Basic 6.0 code. Visual Studio .NET 2003 also includes the Java Language Conversion Assistant, which you can use to convert your Visual J++ 6.0 and Java-language projects to Visual C# .NET.

What's New in the Visual Basic Language
Visual Basic .NET, the next generation of the Visual Basic language, is designed to be a fast and easy way to create .NET applications, including XML Web services and ASP.NET Web applications.

Visual Basic .NET has many new and improved features such as inheritance, interfaces, and overloading that make it a powerful object-oriented programming language. Other new language features include free threading and structured exception handling. Visual Basic .NET fully integrates the .NET Framework and the Common Language Runtime, which together provide language interoperability, garbage collection, enhanced security, and improved versioning support.

Visual C# Language
Visual C# (pronounced C sharp) is a new programming language introduced in Visual Studio .NET. An evolution of C and C++, C# is simple, modern, type-safe, and object-oriented. It was designed for building a wide range of enterprise applications that run on the .NET Platform. Code that you write with Visual C# is compiled as managed code, which means it benefits from the services of the Common Language Runtime. These services include language interoperability, garbage collection, enhanced security, and improved versioning support.

Visual C# is fully supported within Visual Studio .NET by project templates, designers, property pages, code assistants, an object model, and other features of the development environment. The library for Visual C# programming is the .NET Framework.
