title: Xamarin Forms Java.Interop error while debugging on IPad Mini
body: <p>I have a Xamarin Forms app that I am trying to debug on I Pad mini connected to a Mac Book Pro.</p>
  
  <p>Using Versions</p>
  
  <p>Microsoft Visual Studio Community 2015
  Version 14.0.25123.00 Update 2
  Microsoft .NET Framework
  Version 4.6.01055</p>
  
  <p>Installed Version: Community</p>
  
  <p>Xamarin 4.1.1.3 (34a92cd)
  Visual Studio extension to enable development for Xamarin.iOS and Xamarin.Android.</p>
  
  <p>Xamarin.Android 6.1.1.1 (7db2aac)
  Visual Studio extension to enable development for Xamarin.Android.</p>
  
  <p>Xamarin.iOS 9.8.1.4 (3cf8aae)
  Visual Studio extension to enable development for Xamarin.iOS.</p>
  
  <p>The Mac Book Pro is running Simulator 9.3.</p>
  
  <p>When I use the emulator the application runs fine, but when I try and run it on The Ipad Mini I get the Error</p>
  
  <pre><code> Error      Failed to resolve assembly: 'Java.Interop, Version=0.1.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'Client.UI.iOS  C:\Program Files (x86)\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets   681
  </code></pre>
  
  <p>It makes me want to point the finger at Newtonsoft.Json but we have tried to remove that (which is required) and it still doen't work</p>

  <p>This doesn't happen on all Apps, but now it will start to be a blocker as I need to write functions that require the use of the camera.</p>
  
  <p>**** UPDATE **** </p>
  
  <p>My College came back from holiday and discovered that it was because in the UI project we had a reference to Mono.Android,k removing this fixed the build</p>
