.NET Development

A whole raft of new software development opportunities has been created with the advent of the Microsoft .NET platform. The requirement for connected software components and their associated development tools is fast increasing (IDC and Gartner Group forecast $5-6 billion by 2004).

These factors, combined with other important industry developments, have convinced the market that most new systems developed using Microsoft technologies will be based on the .NET platform.

Applied Software Solutions  provides bespoke .NET Windows and Web-based development and consultancy services. The reasons for using the .NET platform are manifold as follows.


Microsoft .NET can best be described as the initiative that will allow the Internet to be the basis of a new operating system. The driving force behind .NET is a shift in focus from individual Web sites or devices to new constellations of computers, devices, and services that work together to deliver broader, richer solutions. Users will have control over how, when, and what information is delivered to them. Computers, devices, and services will be able to collaborate directly with each other, and businesses will be able to offer their products and services in a way that lets customers embed them in their own electronic fabric. Simply put, .NET is Microsoft's strategy for delivering software as a service.

The infrastructure and tools to build and operate this new generation of services comprise of three main components:-


The infrastructure for the overall .NET Platform. The Common Language Runtime (CLR) and class libraries (including Windows Forms, ADO.NET, and ASP.NET) combine together to provide services and solutions that can be easily integrated within and across a variety of systems. The .NET Framework provides a fully managed, protected, and feature-rich application execution environment, simplified development and deployment, and seamless integration with a wide variety of languages. The .NET Framework simplifies service and application development by providing features to help developers use XML Web Services as if they were local objects in the developers' preferred development language. Developers will focus their time and efforts on the unique services that give their company a competitive advantage. The result is faster time to market, improved developer productivity, and higher-quality software.

Key components of the .NET Framework:

    • The Common Language Runtime (CLR). The .NET Framework provides a run-time environment called the Common Language Runtime, which manages the execution of code and provides services that make the development process easier. Compilers and tools expose the runtime's functionality and enable the writing of code that benefits from this managed execution environment. Code that developed with a language compiler that targets the runtime is called managed code; it benefits from features such as cross-language integration, cross-language exception handling, enhanced security, versioning and deployment support, a simplified model for component interaction, and debugging and profiling services.
    • A New Language: The new C# programming language is an elegant, simple, type-safe, object-oriented language that brings RAD to the C and C++ developer without sacrificing the power and control that have been a hallmarks of C/C++.
    • Multiple-language capability. The multiple-language capability of the .NET Framework enables developers to use the programming language that is most appropriate for a given task and to combine languages within a single application. Support for the .NET Framework has been announced for over 20 commercial and academic programming languages.
    • ASP.NET. More than the next version of Active Server Pages (ASP); this is a unified Web development platform that provides the services necessary for developers to build enterprise-class Web applications. ASP.NET is a compiled .NET Framework-based environment; applications can be authored in any .NET Framework compatible language, including Visual Basic and C#. Additionally, the entire .NET Framework platform is available to any ASP.NET application. ASP.NET offers significant performance and scalability benefits over previous Active Server Pages (ASP) and COM+ technology.
    • ADO.NET. An evolutionary improvement to Active Data Objects (ADO) that provides platform interoperability and scalable data access. Because Extensible Mark-up Language (XML) is the format for transmitting data, any application that can read the XML format can process data.
    • Windows Forms. A new forms package that enables developers building Windows-based applications to take full advantage of the rich user interface features available in the Microsoft Windows operating system. Windows Forms offers full support for quickly and easily connecting to Web Services and building rich, data-aware applications based on the ADO.NET data model.


The new features of Visual Studio .NET make it a complete development environment for building on the Microsoft .NET Framework. It provides key enabling technologies to simplify the creation, deployment, and ongoing evolution of secure, scalable, and highly available Web applications and XML Web services while leveraging developer skills. Key features of Visual Studio .NET allow developers to:-

    • Speed up with high-productivity development tools. A tightly integrated and unified visual environment simplifies the process of developing Web applications and reduces the learning curve. Shared HTML, XML, and style-sheet editors make it easy to develop Web applications from any Visual Studio language, including the new C# programming language.
    • Rapidly design broad-reach Web applications. With Web Forms developers can create cross-platform, cross-browser programmable Web applications using exactly the same techniques previously employed to build form-based desktop applications. Web Forms execute on the Web server, providing fast run-time performance and generating HTML 3.2-compliant documents that can run in any browser.
    • Easily use XML Web services to simplify distributed computing. With XML Web Services, developers can invoke business logic over the wire using standard Internet protocols. XML Web services utilise HTTP as the underlying transport, which allows function requests to pass through corporate firewalls. XML is used to format the input and output parameters of the request, so that the request is not tied to any particular component technology or object calling convention. As a result, any language, used by any component model, and run on any operating system, can access XML Web services.
    • Quickly build middle-tier business components that scale by default. A key goal of Visual Studio is to provide rapid application development (RAD) tools for server-based development. Visual Studio .NET brings the same level of productivity to creating middle-tier business logic that Visual Basic brought to forms-based development. The components you build can be powerful and scalable enough to run your business. In addition, the Visual Basic Language has been updated with a number of new features, including new object-oriented capabilities.


NET Enterprise Servers are Microsoft's comprehensive family of server applications for building, deploying, and managing scalable, integrated, Web-based solutions. Designed with mission-critical performance in mind, .NET Enterprise Servers provide scalability, reliability and manageability for the global, Web-enabled enterprise and are built from the ground up for interoperability using open Web standards such as XML. The .NET Enterprise Servers build on the foundation laid with Windows DNA. Windows DNA made it possible for companies to create the scalable Web solutions now deployed all over the world; those solutions will be leveraged to create the next generation of solutions as the Web continues to evolve. The fundamental concepts used in building applications based on Windows DNA still apply, and are instructive in understanding how the Microsoft Web solutions platform can help solve real-world customer problems.
