title: Xamarin Forms 4.1.0: Method not found: void .ResourceLoadingQuery.set_Instance(object)
body: <p>SOLUTION</p>
  
  <p><a href="https://github.com/xamarin/Xamarin.Forms/issues/6787" rel="nofollow noreferrer">Solution here</a></p>
  
  <p>Or simply make sure that all projects in your solution using Xamarin Forms are updated.</p>
  
  <p>Original Question</p>
  
  <p>An upgrade to Xamarin Forms 4.1.0.555618 from 4.0.0.425677 is causing a Type Resolution exception and throwing the following error when I try to resolve a class:</p>
  
  <pre><code>Method not found: void .ResourceLoadingQuery.set_Instance(object)   
  </code></pre>
  
  <p>This doesn't happen with version 4.0.0.xxxx.</p>
  
  <p>EDIT This only happens on Android (version 9.0/Pie), and works fine on iOS</p>
  
  <p>If it helps I'm using <a href="https://github.com/grumpydev/TinyIoC" rel="nofollow noreferrer">TinyIoCContainer</a> to resolve any dependencies.</p>
