Xamarin System.objectmodel

Question

I am having trouble creating a xaml shared project. Out of the box creating a new project it will not compile. Seems to be related to system.objectmodel, manually added it from C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\Facades

Same thing; not found. I tried removing the reference, no difference.

I am also getting a conflict warning, for system.runtime

<?xml version="1.0" encoding="utf-8"?>
<configuration>
 <runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
   <dependentAssembly>
    <assemblyIdentity name="System.ObjectModel" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-4.0.10.0" newVersion="4.0.10.0"/>
   </dependentAssembly>
   <dependentAssembly>
    <assemblyIdentity name="System.Runtime" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-4.1.0.0" newVersion="4.1.0.0"/>
   </dependentAssembly>
  </assemblyBinding>
 </runtime>
</configuration>

I hope this is simple. All I have done is create a new xamarin xaml shared project and tried to compile it and it fails. I just don't know the secret-sauce and which assemblies and their locations to use, need a little help to get past this.

Thanks much,

Installing it from nuget might be better than manually adding a reference — Malte R
Tried it.... Updating the packages creates a circular reference with xamarin.forms. First pass, updates to 24.... but then wants to downgrade forms 23.3 after the update, then it calls for the update to 24 again, my head is going to explode... never touches system.objectmodel anyway which is expected, thats is a ms assembly. What version, I am not sure... 4.2? What a can of worms. I think the wheels fell off updating xamarin to 4.2 via tools... Xamarin wants me to burn an msdn incident to get this working, lol.. — surfride
