No matter how much I read about WCF in online forums and blog posts, I still couldn’t grasp the whole idea behind the extensibility model until I was able to play with it myself. What I discovered along the way is how the entire channel model works and...

The 2010 release provided a dramatic shift in the build platform. Previous releases were built on top of MSBuild, providing integration through custom tasks and a special logger for tracking events during a build. Current and future releases are built...

I apologize to my reader or so for the lack of updates recently. I have been knee deep in work for our next release and have not had much spare time. I will also be fixing my code segments soon which are now cut off due to the re-theming of our blogs...

Update 01/20/2009: Since I failed to mention this before I wanted to make something clear about these workflow posts. All information in these posts is based on the knowledge I gained through developing a framework based on Windows Workflow 4.0. I am...

So far we have written ParallelItemScheduler<T> , which is a generic activity that goes dormant and schedules actions based on input via bookmark resumption. We then used this activity to design ProducerConsumer<T> , which takes this idea...

In my previous post I introduced you to NativeActivity and walked through the design and implementation of a class named ParallelItemScheduler<T> . In part 2 of this series we will be utilizing the aforementioned activity to build a new composed...

In my last couple of posts I have lead you through some basic introduction to workflow as well as a real world example of how to implement a cancelable CopyFile activity. The next thing I would like to do is dive into a much more involved example utilizing...

It has recently come to my attention that there is unrest regarding our inclusion of a CopyDirectory activity without a CopyFile activity. Therefore, I decided to take this opportunity to introduce everyone to the sub-class AsyncCodeActivity and how you...

This particular post has nothing to do with technology. I'm an avid college football fan and have always cheered for my alma mater, the Georgia Tech Yellow Jackets. Tonight, for the first time since I have been actively following them, we beat Clemson...

Note: I apologize in advance if this first post seems unorganized. There is a lot of material to cover and I couldn’t find a really good way to order the topics. Hang in there and hopefully it will start making sense. In order to help everyone get...

My previous post introduced the basics of how the tracking participant may be used to create custom build information through the activity context. However, as pointed out at the end of the article, the best practice for creating custom activities in...

Before reading this post, you should take a moment to read Aaron Hallberg’s post on build process customization in TFS 2010 Beta 1. Now that you fully understand custom activities in Windows Workflow 4.0 (just kidding), I would like to focus on how we...

In TFS 2008 we made quite a few improvements to build, such as scheduled builds and continuous integration. The continuous integration feature is nice for detecting failures in the build as soon as possible to ensure minimal downtime and reduce the chance...

Developing a program that does not require administrative privileges requires quite a bit of work up-front during the install. You need to make sure you do things like write registry keys to HKLM, create file system entries, and most importantly ensure...

What software developer can start anything new without the proverbial "Hello, World". Since I'm new to this side of things, this will serve as my introduction. My name is Patrick Carnahan, and I'm currently a developer on a product called Team Foundation...
