This sounds like the F# targets are missing. What kind of project are you trying to build?

Could you try this please from a terminal?

cd /Users/gouri/Projects/testfbugbuild
xbuild /v:diag

I compared the gist attached in comment #2 (failed) and comment #7(passed). In failed gist Language was set to English in Environment->VisualStyle.  Somehow this setting is causing the build error that I am seeing. When I changed it back to default, restarted XS and rebuilt F# project it built fine. 

I believe setting user interface language is causing the issue. 

## Build Logs:
Failed: https://gist.github.com/GouriKumari/cf93cc31e6950ff05b73e95e92c2344a
Passed (after setting language interface to default): https://gist.github.com/GouriKumari/cae610474954d6b4aa7383246ce78aa3
Comment 14 Mohit Kheterpal 2016-08-19 13:37:20 UTC
I am able to reproduce this issue with current alpha builds and observed that this issue has been fixed in Xcode 8 build of XI i.e. xamarin.ios- and cycle 8 build of XI

Now I am able to build iOS application when I set user interface Language to 'English' in XS->Preferences->Visual Style.

Hence closing this issue by marking it as Verified.
