I get the following error (has nothing to do with code I added or changed):
/Users/vkowalski/Projects/XAM110-ex1-start/MyTunes.Shared/SongLoader.cs(12,12): Error CS0012: The type
System.Object' is defined in an assembly that is not referenced. Consider adding a reference to assembly System.Runtime, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' (CS0012) (MyTunes.iOS)
Anyone know why I get this and how to resolve it?
