Meier announces the official release of the Composite Application Guidance for WPF and Silverlight Version 2, often referred to as ‘Prism’. Also, Blaine Wastell shares some screenshots of the sample application from Prism V2 and links to a number of resources about the parts of this release, along with some video content.
• DDD: What Kind of Applications Is It Suited To? – Casey Charlton continues his DDD series with a look at how well Domain Driven Design fits with different types of application development.
• System.Linq.Enumerable.Aggregate – Better Know an Extension Method Part 1 – Chris Hampson gives a nice example rich introduction to the Aggregate Linq extension method.
• Implement Linq to Objects in C# 2.0 – Think Before Coding – Jérémie Chassaing explores how you can implement a lot of Linq like functionality in C#2, looking at how Linq works and how an implementation can be achieved in C#2
• Types of testing – Laila Bougria offers definitions for the various types of testing that can occur in a software project. Many people seem to get bogged down in the idea that testing == unit testing and then actually create ‘unit test’ which are actually different types of test (such as integration test, load test, etc)
• Fluent Interfaces: What am I missing? – David Starr considers what Fluent Interfaces are, and if they are actually useful in many contexts.

• C#: Extensions methods != Open classes – Mark Needham reminds us that extension methods do not mean our classes all instantly become Open Classes (in the sense of the Open Closed principle). One of the key missing features is the ability to override using extension methods.
• Reflection Speed Test – How slow is it really? – Grant Barrington looks at one of the common uses of reflection, to get a name for an enumeration value, and pits its performance against a number of other ways of achieving the same.
• The M Programming Language – Part 2 – Collections and Extents – Bart De Smet continues his series on the M programming language with a look at implementing collections and extents, comparing to implementations in C# and Linq.
