CS1703: In Xamarin.Droid, should I use the .Net Standard windowsruntime.dll located in Mono.Framework, or System.Runtime?

Question

I'm trying to build this Android Xamarin project, and am getting the compile time error:

./ResilientServices/ResilientServices.Droid/CSC: 
  Error CS1703: Multiple assemblies with equivalent identity have been imported:

./ResilientServices/packages/System.Runtime.InteropServices.WindowsRuntime.4.0.1/lib/netstandard1.3/System.Runtime.InteropServices.WindowsRuntime.dll'
 and  
./Library/Frameworks/Mono.framework/External/xbuild-frameworks/MonoAndroid/v1.0/Facades/System.Runtime.InteropServices.WindowsRuntime.dll'. 

 Remove one of the duplicate references. (CS1703) (ResilientServices.Droid)

@JDibble if many projects exist, make sure dll versions are the same among each one. Dependencies matter — makerofthings7, Oct 23 '17 at 12:53

Ran into this just this week. No idea what change caused it.

What worked for me was commenting out the HintPath in the .csproj Reference:

<Reference Include="System.Runtime.InteropServices.WindowsRuntime">
    <!--HintPath>..\..\packages\System.Runtime.InteropServices.WindowsRuntime.4.0.1\lib\netstandard1.3\System.Runtime.InteropServices.WindowsRuntime.dll</HintPath-->
    <Private>True</Private>
</Reference>

Duplicate question here, btw.
