Cannot pair with latest Xamarin for Visual Studio with Xamarin Build Host

I am using the latest Xamarin stable builds on my Mac and Windows machine. Unfortunately I am no longer able to pair with my Mac. It says no UUID is set after attempting a pairing.

    Seems like yet another bug in their latest builds. Read announcement at the top of the forum. Unfortunately none of their work arounds are working for me. Starting to get disappointed by the QA I am seeing. I'm a trial user but starting to wonder if I'll ever go beyond that. Haven't been able to use my trial for over a week now even though they extended it. Was trying to get a working prototype to convince my employers to buy license but all I've shown them is me being unable to use the product so not looking good....

    I followed the copying of the assemblies and facades in that announcement with no luck. On to uninstalling the latest Xamarin and going back to the previous versions. Xamarin Support, lately the experience with your tools has been much less than stellar.

    Hi @RichardCrane.2330‌,

    Thanks for letting us know about the issue! I saw this issue earlier this morning and wrote up a bug report for our Visual Studio Team to further investigate. You may want to cc yourself onto the report to be notified of any updates or fixes to the issue.

    At this point, the only workaround I know of is to downgrade back to Mavericks. However, if I hear of any other workarounds I'll add it here and to the report. Cheers!

    @AllieMiller‌ I downgraded back to Mavericks, but it is still not pairing for me. It was paired previously under Mavericks, I don't know how to get it working again. I re-installed all of the Xcode and Xamarin bits just to make sure they were all there.

    @EricGrover I experienced the same, after install again Yosemite preview 1 the pairing process Works again. But If you install preview 3 or 4, VStudio will not pair with Build Host.

    Just tried pairing Visual Studio 2013 w/Build Host on Yosemite GM. Still fails.

  • I have same issue :( and it's very frustrating!

  • I've disabled the Yosemite Firewall and now works fine :)

  • BrettMorrisonBrettMorrison USMember, University

    Just confirmed, firewall was already disabled for me on Yosemite. Not working.

    It seems the main focus of this thread is the pairing problem on OS X Yosemite, so I'm going to close this as a duplicate of a new thread about that issue to help consolidate further discussion:

    I added a note on the new thread that it might be possible to work around the problem temporarily adding a network proxy between the Mac build host and the Windows machine. I'm not sure if this will really work, but if anyone has some experience with proxies, please do reply on the new thread to let other users know if this might be possible. Thanks!
