I'm speaking at TechEd 2007 in Orlando this coming June on the whys and hows of customizing TFS.  As part of the early research I'm doing for the talk, I'm reaching out to the individual teams to understand what they've seen to date.  I just heard back from Buck Hodges on the Team Build team and he sent me an amazing list of blog posts that I can use as source material.  Since it seems like a great resource for everyone to use, I thought I'd share it with the community:

Aaron’s posts on how to extend team build through custom tasks and a custom logger.  Writing custom tasks is the primary way folks extend team build to do more complex tasks.

General explanation of key v1 API methods

Here are Jason Prickett’s posts on how to filter the build completion event so that folks can control which builds are recorded in WIT for the Found In Build and Resolved In Build fields.

Here are some of my posts.

Wow...I've got some reading ahead of me!

Enjoy!
