Implementation is the creation of software functionality according to design. Includes resolving open low-level design issues while defining primitives for data structures, algorithms, interfaces, and other design elements.

Primary activity is creating code and configuration data to implement functionality using the selected languages, technologies, tools, and environments. Also includes coding practices, debugging, support for testing, performance optimization, integration strategies, and construction planning.

The purpose of implementation is:

• to define the organization of the code, in terms of implementation subsystems organized in layers;
• to implement the design elements in terms of implementation elements (source files, binaries, executables, and others);
• to test the developed components as units;
• to integrate the results produced by individual implementers into an executable system.

Implementation practice involves some or all of the following:

• defining applicable standards and conventions for software coding, documentation and testing;
• operating formal coding standards and procedures (including rules, practices and conventions);
• preparing test plans and developing appropriate test data for each software component and combination;
• identifying the tested components so that traceability to source code versions is possible;
• documenting expected and actual test results;
• identifying any new or changed practices, controlling their introduction into the development or support environment and managing any associated risks.

"The time is right to get serious about this. As software becomes increasingly dominant in the IT industry, and, indeed, in everything else, there is an obvious need for a professional-level recognition. Far too much is placed on particular credentials for specific products or applications without regard to the bigger picture. The result is poorly engineered software projects."

"Commenting is a royal pain in the posterior" - "Comments are for weenies" - "I can understand my code quite well, thank you very much" - "Good code speaks for itself" - "No time for that, got to get that code out of the door". None of these is a good reason for not commenting source code properly. We will look at these arguments, discuss them and take a look at good commenting practice and its benefits.

The SharpDevelop C# Coding Style Guide was written by Mike Krueger. This document can also be read as a guide to writing robust and reliable programs. It focuses on programs written in C#, but many of the rules and principles are useful even if you write in another programming language.

Determining which function or set of functions to use for managing memory in your Win32 application is difficult without a solid understanding of how each group of functions works and the overall impact they each have on the Microsoft® Windows NT operating system. In an effort to simplify these decisions, this technical article focuses on the use of the memory-mapped file functions in Win32: the functions that are available, the way they are used, and the impact their use has on operating system resources. The following topics are discussed in this article:

• Introduction to managing memory in Windows operating systems
• What are memory-mapped files?
• How are memory-mapped files implemented?
• Sharing memory with memory-mapped files
• Using memory-mapped file functions

NAnt is an Open Source product that allows you to perform some powerful build, documentation and deployment solutions for .NET. But normally it's difficult for people to write the NANT build file.

Spring.NET is a port of the Java based Spring Framework. Spring for Java contains a lot of functionality and features, many more than Spring.NET currently offers. The initial release of Spring.NET contains a full featured Inversion of Control container. Subsequent releases will contain support for Aspect Oriented Programming (AOP), ASP.NET, Remoting, and data access. This introduction discusses each of the existing libraries in turn.
