@Jeff - I believe this is a bug in the msbuild logic? Is this something on your side of the house?

If not, pass back to me.

I'm confused. The log says that it is *not* running the _CompileToNative task because the outputs are already up-to-date:

Done building target "_CompileEntitlements" in project "/Users/alan/Projects/md-addins/external/interactive/Xamarin.Interactive.Agents.iOS.Unified/Xamarin.Interactive.Agents.iOS.Unified.csproj" ("/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets"); "_CompileToNative" depends on it.

		Done building target "_CompileToNative" in project "/Users/alan/Projects/md-addins/external/interactive/Xamarin.Interactive.Agents.iOS.Unified/Xamarin.Interactive.Agents.iOS.Unified.csproj"

Yet the title of this bug report says that it is running _CompileToNative when it *shouldn't*?

@Jeff, I think you're looking at the wrong _CompileToNative Task: 

> Building target "_CompileToNative" in project "/Users/alan/Projects/md-addins/external/interactive/Xamarin.Interactive.Agents.Mac/Xamarin.Interactive.Agents.Mac.csproj" ("/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Mac/Xamarin.Mac.Common.targets"); "_CreateAppBundle" depends on it.

> Target _CompileEntitlements skipped due to false condition: '$(EnableCodeSigning)'

Oh, in that case, yes, this is a bug in the targets file. The Outputs value is looking for the exe in the wrong place.
Comment 6 Jeffrey Stedfast 2015-09-08 16:31:12 UTC
fixed in the xcode7 branch
