Answer 1

These non-actionable warnings can be suppressed by editing the following into the Android project file:

<PropertyGroup>
    <MSBuildWarningsAsMessages>XA0106</MSBuildWarningsAsMessages>
</PropertyGroup>

As of Visual Studio 16.3 Preview 1, these have been downgraded to messages instead of warnings, so suppression will no longer be necessary. More background is available on the Xamarin.Android GitHub.
