@kria - do you need any help with this? If my area doesn't get devastated by Hurricane Irma this weekend, I will have some free time to work this if you can help point me in the right direction.

Go for it @dukesta3! Basically you start with the master branch which holds the 2017.2 codebase. You then replace all the dll:s in lib\ with the corresponding files from Application Tier\Web Services\bin\ of a new TFS 2018 RC1 installation. Compile, test and fix what breaks. Since it's a new major version, the breaking changes may be extensive, but I really have no idea.

Stay safe!

@kria - we got this working by adding the new libs and changing one line of code. We are just moving over from Jira and Stash, so have only tested work item and pull requests being pushed to HipChat Server. I can send you a PR if you want, let me know what branch you want to merge into.

I added a new branch tfs2018, that you can merge into. Thanks!
