Okay here's the answer! I had a local reproduction of this and it seems that there are some references missing in the .csproj:
Please ensure the following is added to your .csproj
as References:
<Reference Include="Xamarin.Android.Support.Design, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
<HintPath>....packagesXamarin.Android.Support.Design.23.0.1.3libMonoAndroid403Xamarin.Android.Support.Design.dll</HintPath>
<Private>True</Private>
</Reference>
<Reference Include="Xamarin.Android.Support.v4, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
<HintPath>....packagesXamarin.Android.Support.v4.23.0.1.3libMonoAndroid403Xamarin.Android.Support.v4.dll</HintPath>

</Reference>
<Reference Include="Xamarin.Android.Support.v7.AppCompat, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">

<Reference Include="Xamarin.Android.Support.v7.MediaRouter, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">

You can then remove the Resource.designer.cs
