Cheap Microsoft Visual Studio .NET Enterprise Developer 2003 Upgrade from 2002 (Software) (Windows 95, Windows 2000, Windows Me, Windows 98) Price

Microsoft’s .NET tools are very different from their predecessors. Visual C++ can still compile standard Windows executables, but the other languages all target the .NET Framework, a runtime engine and class library that manages memory and enforces security. Framework applications perform well, since they are compiled to native code at runtime, but there is an overhead in terms of memory usage and the Framework runtime must be installed. In compensation, .NET brings many advantages. All the languages are fully object-oriented, the class library is rich, and XML support is fully integrated. ASP.NET is for web applications, and represents a large advance on the old ASP. Instead of script, ASP.NET supports any of the .NET languages, running on the server and just-in-time compiled to native code. There is a visual web page designer, and carefully designed applications support a wide range of browsers. New in this version of Visual Studio is Mobile Web Forms, which use adaptive rendering to support the browsers in mobile phones and PDAs. The database technology in Visual Studio is called ADO.NET, and uses a disconnected model that is ideal for laptops, smart devices, and wide area networks.

Visual Studio .NET Enterprise Developer 2003 earns its name by including developer licenses for the key Microsoft server platforms, including Windows Server 2003, Exchange 2000 Server and SQL Server 2000. Another key component is the Visual SourceSafe code management system, which is especially important for team development. There is also Application Center Test, for stress-testing web applications.

For those wondering whether to make the jump to .NET, this release is probably the right moment to go ahead. The technology is maturing, and the inclusion of the Compact Framework makes the package more compelling. The deep XML support on offer is essential for many enterprise applications and enables integration with other platforms. It’s still important to note the heavy system requirements, and that .NET applications do not run on Windows 95. In most cases, the higher productivity of .NET languages soon pays for any additional resources. --Tim Anderson, Amazon.co.uk
