Almost every programmer knows (unless you have been living under a rock for the last five years or so) that you should be using classes for all of your programming. You should also be using collections of objects instead of using a Data Reader, a DataSet, or a DataTable in your applications. The reasons for using collections are many and are explored in this article.

Understanding Dependency Injection and Those Pesky Containers

We seem to be an industry enamored with buzz words. Even though XmlHttpRequest has been around since the mid-90s, mainstream programmers didn’t give it a second thought until someone attached the term AJAX to it. The same is true for the never-ending quest to put as many different words as we can in front of “driven-development.” Another term that hit the scene in recent years is dependency injection.

If you are a .NET software developer, you have heard of F#. You may have read an article, seen a talk at a user group, or otherwise heard the buzz. However, if those means of reaching you have failed, at the very least, you have noticed it conspicuously appear in the list of languages you can base a solution on in Visual Studio 2010. If you write code on the .NET Framework, you would have to be living under a rock to have not heard of F#.

The Entity Framework team at Microsoft has been making several improvements since the launch of v4 with Visual Studio. The biggest of these is the capability to use a Code First or Code Only development model. Previously, if you wanted to work with the Entity Framework, you had to use either a Database First or Model First development model.

POCO Support Comes to Entity Framework 4

Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2010 - November/December
When Microsoft first released the Entity Framework, agile developers roundly criticized it. These developers hold the tenets of domain-driven development and testability very high. The classes generated from the Entity Data Model (EDM) are very tightly bound to the Entity Framework APIs by either inheriting from the EntityObject or implement interfaces that allow the classes to participate in change tracking and relationship management.

Derick outlines how to achieve the benefits of low coupling, high cohesion, and strong encapsulation. He also shows how the five S.O.L.I.D. design principles can get you there.Most professional software developers understand the academic definitions of coupling, cohesion, and encapsulation.However, many developers do not understand how to achieve the benefits of low coupling, high cohesion and strong encapsulation, as outlined in this article. Fortunately, others have created stepping stones that lead to these goals, resulting in software that is easier to read, easier to understand and easier to change. In this article series, I will define three of the primary object-oriented principles and show how to reach them through the five S.O.L.I.D. design principles.

Bricks and Mortar: Building a Castle
By:
Kovacs, James
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2009 - May/June
In an application built with object-oriented techniques, objects are the bricks.You construct little pieces of code encapsulated in these bricks. To build bigger structures, you need to hold these bricks together. You can hardwire them together by instantiating dependent objects within your objects, but it makes the whole structure less flexible in the face of change. So you can adopt an inversion of control (IoC) container to act as your mason to assemble your bricks into complex structures that can flex with changing requirements. In this article, I will examine a popular IoC container, Castle Windsor, and how it enables you to build flexible and robust applications. If you are new to IoC containers and dependency injection, I would recommend reading Martin Fowler's article, Inversion of Control Containers and the Dependency Injection Pattern (http://martinfowler.com/articles/injection.html) and my own article from the March 2008 edition of MSDN Magazine, Loosen Up: Tame Your Dependencies for More Flexible Apps (http://msdn.microsoft.com/en-us/magazine/cc337885.aspx).

ASP.NET Development Through Web Controls and Declarative Programming
By:
Last updated: Wednesday, February 20, 2019
Published in: CODE Magazine: 2005 - March/April
ASP.NET WebControls do more than just allow you to write reusable components. They can provide an entire approach to Web application development, allowing you to bring a new level of OOP to the UI and letting you program declaratively.Lately I've come to notice that no other programming term has more definitions than declarative programming. In this article, I will attempt to explain it in terms of how it applies to .NET development, specifically ASP.NET through the use of WebControls. I'll do this by illustrating some real-world examples that I have used in my own projects. In the end, I hope to leave you with an understanding of what declarative programming is, how you can use it when developing ASP.NET Web applications, and how, with the help of WebControls, to use it as an approach to ASP.NET development.

Have you ever wanted to use a strongly-typed collection to bind your data presentation controls to, only to find that you have very limited sorting capabilities, if any at all?If you are trying to stick to good object-oriented design and shrink the amount of data that you keep in memory, transfer from your data source, or serialize to clients, you likely have run into this situation because you are using strongly-typed collections of your domain objects. So what do you do if you need to sort those collections for presentation or faster searching?

Working with Extender Classes

Extender classes do just that; they allow you to extend the functionality of a .NET control class. The Error Provider and Tooltip classes are two examples of extender classes in the .NET Framework. The Tooltip class represents a significant departure from how tooltips were implemented in earlier versions of Visual Studio. The Error Provider class provides a new way to inform users about invalid input. Although each class serves a different purpose, their implementation is quite similar. This article introduces these two classes and gives a brief, yet comprehensive primer on how to use them

.NET Interface-based Programming
By:
Lowy, Juval
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2002 - May/June
In component-based programming, the basic unit of use in an application is a binary-compatible interface.The interface provides an abstract service definition between the client and the object. This is in contrast to the object-oriented view of the world that places the object implementing the interface at the center. An interface is a logical grouping of method definitions that acts as the contract between the client and the service provider. Each provider is free to provide its own interpretation of the interface and its own implementation. To use a component, the client only needs to know the interface definition and have a binary component that implements that interface. This extra level of indirection between the client and the object provides for interchangeability between different implementations of the same interface, without affecting client code.
