I did a session at the Boston Area SharePoint User’s Group (BASPUG) on 8 December called "Developing in SharePoint’s Middle Tier". Thanks to all who attended! I enjoyed the conversation during the session (I like discussing more than presenting) and one of the things I said that I would do is make the demo site I used available to anyone who’d like to look at it.
I saved the SharePoint 2010 site as a Site Template, and it’s available for download from my Sympraxis Consulting demo site.
Feel free to download the template and play around with it. If you have any questions, don’t hesitate to add them as comments to this post.
