Description Chris Hamons 2015-10-02 16:49:52 UTC
0) Install C6 build (alpha)
1) Create new XM project 
2) Build (note that building works fine)
3) Note that AppKit/Foundation/Register/NSApplicationDelegate are all red
4) Right click any of them. Note that each of them wants you to reference Xamarin.Mac (which is already in the references list) before it will work.
5) Note that auto complete is totally busted.
Comment 1 Chris Hamons 2015-10-02 16:56:34 UTC
Rolling back to stable XM (Version: (Business Edition)) had zero effect.

Are there any parts of the environment that are different for you Chris? I have a PR build of XS installed, but that's it.
Comment 3 PJ 2015-10-02 16:57:47 UTC
I'll roll back to the XS in Alpha to be sure as well.
Comment 4 Chris Hamons 2015-10-02 17:00:16 UTC
I had 800 (current alpha). Trying 803 from pipeline.
Comment 5 PJ 2015-10-02 17:00:42 UTC
Same result with Alpha XS (92083188182e8c4588153e0d63e99c1a7037e4b6), works for me here.
Comment 6 Chris Hamons 2015-10-02 17:16:35 UTC
It appears Library/Caches/XamarinStudio-5.0/DerivedData was corrupted somehow. Once I nuked it, that "fixed" it. Tracking down exact file shortly.
Comment 7 Chris Hamons 2015-10-02 17:20:35 UTC
Created attachment 13184 [details]
The corrupted cache

Comment 8 Chris Hamons 2015-10-02 17:21:09 UTC
If I nuke my cache for XS, launch, then take that zip and apply it, then I get the "broken" behavior.
Comment 9 xamarin-release-manager 2015-10-05 01:34:55 UTC
Fixed in version (master)
