Description Dimitar Dobrev 2016-10-21 14:01:11 UTC
I have a regular (non-portable) MonoTouch library dependent on a portable library which uses .NET 4.6 (profile 44). When trying to compile the MonoTouch library with Xamarin Studio on OS X, I get:

 The type `System.Object' is defined in an assembly that is not referenced. Consider adding a reference to assembly `System.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

It works fine when compiling the exact same code with Visual Studio.

I can reproduce reported issue, I have attached a test case that reproduces described scenario on comment #0
Comment 3 Dimitar Dobrev 2016-10-28 11:53:58 UTC
Any approximate release date for the fix?
Comment 4 Marek Safar 2016-11-24 11:33:40 UTC
This looks like xbuild issue where PCL library reference does not add PCL library dependencies.
Comment 5 Alexander Köplinger [MSFT] 2017-06-14 00:09:14 UTC
This seems to work now in VS4Mac (with both xbuild and msbuild).
