This is only happening when building from the command line but our nightly build is failing with the following error:

"E:\Jenkins\jobs\CloudApps\workspace\Dictation\Dictation.iOS\Dictation.iOS.csproj" (default target) (7) ->
(_GetNativeExecutableName target) -> 
  C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(705,3): error : Could not load Info.plist: Could not find file "/Users/<OurUserName>/Library/Caches/Xamarin/mtbs/builds/Dictation.iOS/4cf4fed2df1a51fa4939c266aca0972c/bin/iPhone/Release/Dictation.iOS.app/Info.plist". [E:\Jenkins\jobs\CloudApps\workspace\Dictation\Dictation.iOS\Dictation.iOS.csproj]

    5 Warning(s)
    1 Error(s)

The only other issues are warnings about mismatch between MSIL and x86 versions of mscorlib. This started happening when our junior dev decided to update Xamarin Studio and when it prompted him to install VS for Mac, he did that. So it added VS to the Mac and now the above error. We have not removed Xamarin Studio if that makes a difference. Anyway, here is the version info from the new VS install:

Hi jcraig,
Sorry for the late response. I've been trying to reproduce this issue but unfortunately I couldn't hit it, so I have a couple of questions for you that might help me to find the issue:
1) Are you still able to reproduce this issue?
2) Did you update Xamarin for Visual Studio (Windows side) after installing VS for Mac? VS for Mac installs a new version of Xamarin.iOS on the Mac, and it should be on sync with the Xamarin.iOS installed on Windows.
3) Could you attach the Visual Studio (Win) environment info from the bot that's running your nightly builds (Help -> About Microsoft Visual Studio -> Copy Info)?
4) Could you attach a full diagnostic build output?

Comment 2 jcraig 2017-07-20 13:21:25 UTC
I just talked to the team members who took over the mobile development. Apparently the issue no longer occurs. They've updated both the Windows and Mac side and it went away. Unfortunately they are unable to pinpoint for me when it went away as they were doing the builds manually for a while before noticing the build server was back to normal. I think at this point you guys can probably close the issue.
Comment 3 Emanuel 2017-07-20 20:45:31 UTC
Thanks for the confirmation jcraig! Please, keep in mind to keep both Xamarin.iOS versions (Windows and Mac side) on sync. If you update VS for Mac, you'll need to update Xamarin for VS on Windows, and that's probably what fixed your team's issue.

I'm marking this bug as Not Reproducible per comment2.
