Error compiling Forms.Droid with new release
/Users/MacOwner/xProjects/CareRing/Droid: Error XA0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com. Reason: System.IO.FileNotFoundException: Could not load assembly 'CareRing.iOS.exe, Version=, Culture=neutral, PublicKeyToken='. Perhaps it doesn't exist in the Mono for Android profile?

Why on earth is the Droid build interested in CareRing.iOS.exe?!

Please provide diagnostic build output and we can figure that out. :-)

DIagnostic Build Output
Here you go.
One puzzling thing right off the bat: log shows a build of the IOS target. But this was Right-click menu Build CareRing.Droid. Not a build all or rebuild all.
...and here's the weird part:
> Target _ResolveLibraryProjectImports needs to be built as output file 'obj/Debug/libraryprojectimports.cache' does not exist.
> Task "ResolveLibraryProjectImports"
> Using task ResolveLibraryProjectImports from Xamarin.Android.Tasks.ResolveLibraryProjectImports, Xamarin.Android.Build.Tasks, Version=184.108.40.206, Culture=neutral, PublicKeyToken=null
> ResolveLibraryProjectImports Task
> ImportsDirectory: library_project_imports
> OutputDirectory: obj/Debug/
> OutputImportDirectory: obj/Debug/__library_projects__/
> UseShortFileNames: False
Additional context, from Xamarin.Android.Common.targets:
Why is CareRing.iOS.exe referenced? Because it's part of @(ReferencePath) or @(ReferenceDependencyPaths), i.e. one of your project references, somewhere, claims to depend upon CareRing.iOS.exe.
This output is also "interesting":
> Done building project "/Users/MacOwner/xProjects/CareRing/iOS/CareRing.iOS.csproj".
> Done executing task "MSBuild"
> Done building target "ResolveProjectReferences" in project "/Users/MacOwner/xProjects/CareRing/Droid/CareRing.Droid.csproj".
This implies that CareRing.Droid.csproj has some kind of project reference to the CareRing.iOS.csproj project, presumably a <ProjectReference/>.
Looking earlier still, I find:
> Done building target "SplitProjectReferencesByExistent" in project "/Users/MacOwner/xProjects/CareRing/Droid/CareRing.Droid.csproj" ("/Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/4.5/Microsoft.Common.targets"); "ResolveProjectReferences" depends on it.
> Target ResolveProjectReferences:
> Task "MSBuild"
> Using task MSBuild from Microsoft.Build.Tasks.MSBuild, Microsoft.Build.Tasks.v4.0, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
> Global Properties:
> Project "/Users/MacOwner/xProjects/CareRing/iOS/CareRing.iOS.csproj" (GetTargetPath target(s)):
which further suggests that CareRing.Droid.csproj has a hard/explicit dependency on the CareRing.iOS.csproj project.
Not a jot of code changed between previous successful compiles and this one. Only change was the 'stable' update. Checking csproj files.
Droid csproj contained the following
However removing that clobbered all the Interface references to to base forms project.
Since this was a Forms project, the .csproj ref:
Should have been a reference to the common code csproj:
I never edit these files by hand. And it all compiled nicely before the upgrade to 'stable'. So, how that ref. got clobbered in the upgrade is probably the question that needs answering.
I am back on track but gun-shy about the upcoming 6.0 release
