1.3.2 .NET Enhancements Software development for the PC has developed through the use of languages such as C++, Delphi and Visual Basic. These languages are all focused on producing Windows‐based programs using the x86 architecture. The computing industry, though, has moved over the last few years, with the advent of the Internet and Java. With Java, Sun Microsystems have tried to produce programs which could be run on any type of hardware. This has the advantage that the program can be produced for a range of hardware, including Apple‐based computers and hand‐held devices. There has also been a move toward using software routines which are not necessarily based on the host computer, and in integrating WWW services with programs. This integration is illustrated in Figure 1.2. In general the current weaknesses of software development which have been overcome with .NET are: duction to .NET Intro • Lack of support for different hardware. .NET overcomes this in a similar way to Java in that it produces an intermediate code known as MSIL (Microsoft Intermediate Language) which when run with the CLR (Common Language Runtime) produces an executable program which matches the hardware. • Difficult to integrate different programming languages. This is a problem with most software development environments, especially in representing the variables in the same way. .NET overcomes this by producing a standardized system for data representation, known as CTS (Common Type Representation). The compiler also uses CLS (Common Language Specification) to produce code which can be integrated with other programming languages. Along with this the .NET framework uses a FCL (Framework Class Library) which is a common set of classes which can be used with the different languages. • Lack of security integration. .NET binds itself with the operating system so that it integrates better with the security controls of the system. • Poor version control of system components. .NET improves this by supporting the installation of different versions of the .NET framework. Users can choose which of the version they install, and previous versions will be stored on the host. • Weak integration with the WWW/Internet. .NET integrates WWW development with code development by integrating ASP with VB/C#. In order to support these advancements, Microsoft has developed Visual Basic further and integrated it with ASP, to produce VB.NET. C++ has also been advanced to C# which incorporates many of the advanced features of Java. Figure 1.3 outlines some of the key features of the .NET framework. Agilent .NET Course: Introduction 8
