This is the source code for a tool to deep copy work items in Team Foundation Server. The initial version of this tool has been published years ago (2011) here for Team Foundation Server 2010: https://visualstudiogallery.msdn.microsoft.com/cd89c5d3-4816-4f22-b04e-a397cc606be6
The tool copies all work items related to a work item you select. It creates a "history link" to the original items. See details here: https://visualstudiogallery.msdn.microsoft.com/cd89c5d3-4816-4f22-b04e-a397cc606be6
This was rather a proof for feasibility than a product. Be aware that the tool and the code have some rough edges and usability might be limited.
Use it, modify it, update it - do whatever you want. Of course I'm happy to hear from you where my code goes into but I'm even happier if it is used at all.
Since the day of release several people asked me to update or open source the tool. Things were a little complicated as the actual owner of the source code wasn't me but my former company. It turns out that my previous employer is still pretty awesome and is fine with open sourcing the code. So if you benefit from the code be aware that the guys at http://www.conplement.de/ are the true heroes here and feel free to give them a thumbs up on their facebook page: https://www.facebook.com/conplement/?ref=ts&fref=ts.
