Unit 42 Programming in .NET
To provide learners with an understanding of the principles of programming using a .NET framework as an underpinning technological concept in the fields of programming and systems development.
· Unit abstract
The .NET framework defines a range of reusable class libraries that define the interactions used for Windows operating systems based development of utilities, applications, web based resources, games as well as data integration.
Whilst specific to Microsoft products, the .NET framework defines interactions with servers, workstations and mobile devices. The .NET framework also describes interactions and data exchange with other programming and development systems and is designed to enable cross- platform interaction.
This unit allows learners to become familiar with the underpinning concepts of .NET framework programming, without needing to develop particular skills in one chosen language. Each of the languages has the capacity to develop event driven solutions and it is not important which language is chosen as long as the skills being developed and evidenced relate to the key .NET focus.
The focus of the unit is on developing solutions to meet identified user needs while emphasising the importance of testing and reviewing.
· Learning outcomes
On successful completion of this unit a learner will:
- Understand the principles of programming using a .NET framework.
- Be able to design .NET solutions
- Be able to implement .NET solutions
- Be able to test and document .NET solutions.
1 Understand the principles of programming using a .NET framework
Version: current version; backwards compatibility; design considerations; alternative implementations
Design features: interoperability, common runtime engine, language independence, base class library, deployment, security, portability
.NET languages: eg C#, C++, F#, J#, PowerShell, JScript .NET, IronPython, IronRuby, Visual Basic, IronLISP, L#, P#
Architecture: Common Language Infrastructure (CLI), assemblies, metadata, security, class library, memory management; framework versions (architecture) eg 3.5, 3.0, 2.0; common language runtime and the .NET framework class libraries
2 Be able to design .NET solutions
Selection: identification of .NET compatible programming language, identification of .NET programming libraries, selection of development environment
Design methodology: reuse of existing system, adaptation of code, GUI template, graphical interface, design guides, state and interaction diagrams, screen layouts, data storage, event procedures and descriptions
Specification: input, output, processes, user need, purpose
Creation of application: use of development environment; debugging
Delivery environment: mobile, handheld, web based, desktop, dedicated device, server
Interaction: exchange of data, compliance, compatibility, recognition of standards employed, environment
3 Be able to implement .NET solutions
Tools and techniques: use of tool boxes and controls, selection, loops, event handlers, event driven triggers, listeners, objects and object properties, menus, debugging tools
Data: variables, data types, declaring variables, scope of variables, constants
Programming: use of methods, use of ‘traditional coding’
Complexity: multiple .NET
classes; multiple code elements
4 Be able to test and document .NET solutions
Mechanisms: valid declarations; debugging code; comment code; naming conventions; checking functionality against requirements; documentation
Error handling: management of extremes, use of system imposed statements, interaction between .NET classes
Impact testing: range testing, input testing, load testing, system compatibility
Feedback: record feedback, eg surveys, questionnaire, interviews; analyze feedback; present results
Documentation: user eg onscreen help to assist users of the programme, pop-ups,
help menu, hot-spots; technical eg designs, delivery system, platform,
environment, file structures, coding, constraints, documentation for
maintenance of programme
