"A component must not execute more than 20 SQL statements". A relative new discipline to enforce these types of architectural rules is Dynamic Architectural Validation. We wrote a chapter on the best practices and show how to repurpose your existing unit and functional tests. This allows you to identify architectural regressions that have been introduced with code changes by comparing the dynamic behavior between test runs.

If you are new to BDD you may want to read BDD to the rescue first. This is an introduction and a start of a series about bddify, a powerful BDD framework for .Net, called 'Bddify In Action':

New DI container that combines two aspects that I've been always missing in combination in other DI frameworks. Performance and(!) a rich set of features

Are you looking for a solution to your unit tests modifying data? Perhaps your unit tests are so slow that none of your teammates bother running them? You need mock objects.

The using directive of the C# programming language is often used to create namespace aliases, allowing types with matching names that appear in separate namespaces to be easily accessed. A lesser known use of the directive is to create aliases for types.

At the BUILD conference last September (buildwindows.com), Microsoft unveiled the next version of Windows Workflow Foundation (WF 4.5) and made available a public preview as part of the Windows 8 Developer Preview (msdn.microsoft.com/windows/apps/br229516). In this article, I’ll walk through the key new features added in WF 4.5. Given the general scope of the article and the size of the feature set, each discussion will be brief, but I hope you’ll get excited enough to download the Windows 8 Developer Preview and start playing with WF 4.5.

In this second installment of the useful abstractions, I discuss the WindowBuilder.

It was another hot day; the classroom was almost empty, only those who were brave enough to try to pass the test were left. I wanted that one. I could feel it. I could pass that test. But I was in the state of mind break that time. "What the frog does 'i++' means??”, I thought.

In this article we are going to see how to play around with the Media Player Launcher task, with this Media Player task we can provide with in the application to launch a media player and play a video or audio file. We can provide a list of media files that can be played one by one, along with we have option to make use of the Media play back controls like rewind and stop to skip or rerun the media file. Media file location can be as a resource file or we can also use an Isolated storage to store and retrieve the file while rendering the player to play the respective file. Let us see the steps on how to use this task in a Windows Phone application development.

Extension methods were first introduced with LINQ in C#3.0. They are just a syntactic construct, but as we’ll see in this post they can make a huge difference to the readability.

Over the past year I was involved in the process of interviewing candidates for both mid and senior level developer positions. We would bring them in for a face-to-face interview, sometimes with multiple interviewers, only to find out they were unable to answer the most basic technical questions concerning C# and .NET. I’m of the persuasion that every .NET developer should understand basic concepts, such as C# language syntax, inheritance, generics, memory management, threading, etc. Without such an understanding, a developer can end up writing apps that are shot-through with problems that make the code difficult to debug and maintain.

There where many good ideas and your truly suggested using PostSharp – mainly because this is one of the examples I use in my AOP and PostSharp presentation. And so without further ado here is my solution for your consideration:

Can you remember the last time you tried to search your code base for a relevant method or code snippet? I can, and it was a disaster. I used Visual Studio’s “Find in Files”, which returned 100s of results. After reviewing about twenty of them I gave up and started surfing the Solution Explorer, opening files one-by-one. After about 20 minutes of reading source files I began to wonder if there was a better way...

We’ve just added support for WebAPI to provide per-controller-type configuration. WebAPI has a HttpConfiguration object that provides configuration such as: route table Dependency resolver for specifying services list of Formatters, ModelBinders, and other parameter binding settings. list of message handlers,

After pondering the results of our message queue shootout, we decided to run with Rabbit MQ. Rabbit ticks all of the boxes, it’s supported (by Spring Source and then VMware ultimately), scales and has the features and performance we need. The RabbitMQ.Client provided by Spring Source is a thin wrapper that quite faithfully exposes the AMQP protocol, so it expects messages as byte arrays.

This article briefly describes the main benefits of using generics in c#

To celebrate its sixth month on the web, Windows Phone Parent has launched Familia Windows Phone, the first Spanish review site for Windows Phone apps that enhance the lives of kids and their parents. The Spanish counterpart of Windows Phone Parent, Familia Windows Phone caters directly to key markets like Argentina, Chile, Colombia, Mexico, Peru, and Spain, and its launch has been described as a logical next step for the Windows Phone Parent team.

SaaSpose.Slides API includes all the required functionality for working with PowerPoint Presentation file formats starting with the most popular Microsoft formats: PPT and PPTX format.

Since SSHA (Salted SHA1) is now most commonly used in storing password hashes in OpenLDAP, folks who need to create accounts on this system from .NET (ex. Forefront Identity Manager FIM), may find this sample useful.
