In this article, we take a look at what’s involved with building a simple Twitter Search client for Windows Phone. We will cover what tools you need, where to download them, how to design, build and test the app and finally, how to publish it to the Windows Phone Marketplace.

What is the one activity or phase that improves the quality of your application? The answer is an easy one: Testing, and plenty of it. Traditionally, testing is a phase somewhere towards the expected end of the project - when the cost of any code or requirement changes is known to be much higher. Craig looks at how TDD can address this by adopting a more agile approach.

The accelerated speed of Web development requires streamlined techniques for the entire process, including testing. Here, you learn how to efficiently test Web apps in Visual Studio 2012.

Dr. McCaffrey this month presents a greedy algorithm as a solution to the graph maximum clique problem, which is to find the largest group of nodes in a graph that are all connected to one another. He explains how to design and test these algorithms to solve the problem.

Sometimes an application needs to interact with the user interface (UI) of a second application. The first application might be a test application that drives the UI of the target to run through some automated tests. It might describe the UI out loud, as an aid to users that are blind. It might be a speech application that allows users to give vocal commands. In each of these cases, the application needs a way to inspect and interact with the UI of the system and other running applications.

Networks can model all sorts of situations including physical networks as well as non-physical situations. Learn how to use network algorithms to test connectivity, build inexpensive connections, assign work, and split networks as inexpensively as possible.

Learn to use Visual Studio Team Edition's built-in unit test generation and code coverage analysis capabilities to ensure all your code gets tested.

When you're working on a project, you rarely have the time (and sometimes even the desire) to go back and re-factor code to make it either a) perform better, or b) easier to maintain. Further, you don't have the time to regression test your changes, so the common (and most recommended) practice is to "leave well enough alone". I am fortunate to be in a position to perform such optimizations because my schedule is somewhat flexible (I'm the "pioneer") and I'm waiting for the IT folks to resolve a server issue.

This article shows how I implemented something in my code, and should only be used as an example of how to achieve similar results in your own application…

This article presents an example on unit testing of Silverlight applications with asynchronous service callbacks.

The CODE Framework provides a set of tools for developing n-tier, service-oriented applications. In addition, there is a set of recommended patterns and practices that provide guidance in enabling developers to achieve Rapid Application Development, Contract-First implementation, and a system that allows you to change a contract without breaking an implementation. However, one question which has been repeatedly asked throughout our trainings and seminars is, “How do I Unit Test when I’m using the CODE Framework?” This article will examine the question and attempt to answer it.
