.NET Visualization: Visualizing Information with .NET
Having the capability to draw pictures usually isn’t enough for a good information visualization platform. The key to building a visualization platform is capabilities such as interactivity, generating metadata, and overlaying related data. You need a level of flexibility that lets you render any data in any way at any time. Laurence Moroney
Entity Framework: N-Tier Application Patterns
This article examines n-tier patterns for success and some of the key APIs and issues specific to the Entity Framework. It also provides a sneak peak at features coming in the Microsoft .NET Framework 4 that should make n-tier development significantly easier. Daniel Simmons
Domain Models: Employing the Domain Model Pattern
In this article, we’ll go through the reasons to (and not to) employ the domain model pattern, the benefits it brings, as well as provide some practical tips on keeping the overall solution as simple as possible. Udi Dahan
EF Data Access: EF v2 and Data Access Architecture Best Practices
Developers deploy a wide variety of development philosophies and architecture styles. This article explores three common perspectives on application development and describes how the Entity Framework can be employed in each. Specifically, the article looks at the forms-centric, model-centric, and code-centric development styles and their relationship to the Entity Framework. Tim Mallalieu

Toolbox: Data Snapshots, Subversion, Source Code Organization and More
If you want to save, organize, and annotate snapshots of your database data, find an easy way to install and configure Subversion, and automate the organization of your source code, then you'll want to read more about these latest tools. Scott Mitchell
CLR Inside Out: Code Contracts
This article will share some of the best practices that the Base Class Libraries (BCL) team devised as they added the code contract libraries and started to take advantage of them in their own code. Melitta Andersen
Data Points: Data Performance and Fault Strategies in Silverlight 3
In this month’s column, the author shows how binary encoding works, the effect it has on an application’s performance, and how it behaves by demonstrating it in action. John Papa
Cutting Edge: Pros and Cons of Data Transfer Objects
After a brief refresher on procedural and object based patterns for organizing the business logic layer, the author focuses on data transfer objects and the impact they have on the development of the software project. Dino Esposito
Patterns in Practice: Incremental Delivery Through Continuous Design
The end goal of software projects is to deliver value to the customer. Software design is a major factor in how successfully a team can deliver that value. The best designs are a product of continuous design rather than the result of an effort that tries to get the entire design right up front. This approach lets you strive to apply lessons learned from the project to continuously improve the design, instead of becoming locked into an erroneous design developed too early in the project. Jeremy Miller
Security Briefs: Cryptographic Agility
Even if you use only the most secure algorithms and the longest key lengths, there’s no guarantee that the code you write today will remain secure. A better alternative is to plan for agility from the beginning. Rather than hard-coding specific cryptographic algorithms into your code, use one of the crypto-agility features built into the Microsoft .NET Framework. This article shows you how. Bryan Sullivan
Under the Table: How Data Access Code Affects Database Performance
In this article, the author delves into some commonly used ways of writing data access code and looks at the effect they can have on performance. Bob Beauchemin
Foundations: Windows Workflow Design Patterns
Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF. Matthew Milner
.NET Matters: Aggregating Exceptions
Exceptions in .NET are the fundamental mechanism by which errors and other exceptional conditions are communicated. This month’s column provides information about how to aggregate exceptions to help manage a variety of scenarios in which multiple exceptions might result from one operation, including scenarios involving parallelism and concurrency. Stephen Toub
