title: Can't set Build Action to GoogleServiceJson
body: <p>I'm working with Xamarin-Android to make an application, so I need to set Build Action to my google-services.json file but there is no such Property as GoogleServicesJson, and when I try just to write it, it shows me an exception: </p>
  
  <blockquote>
    <p>Exception of type 'System.Runtime.InteropServices.ExternalException'
    was thrown.</p>
  </blockquote>
  
  <p>I tried to save and then restart Visual Studio, but it didn't solve the problem.</p>
  
  <p>If you know how to solve this problem, please help me! :)<br>
