body: <p>I just upgraded from MvvmCross 3.5.1 to MvvmCross 4.0. I'm getting around 40 errors like this when building Android in the Resource.Designer.cs file. </p>
  
  <p>iOS works fine. </p>
  
  <pre><code>error CS0117: 'ProjectName.Droid.Resource.Styleable' does not contain a definition for 'Theme_seekBarStyle'
  </code></pre>
  
  <p>The line of code looks like this. </p>
  
  <pre><code>global::Chance.MvvmCross.Plugins.UserInteraction.Droid.Resource.Styleable.Theme_seekBarStyle = global::ProjectName.Droid.Resource.Styleable.Theme_seekBarStyle;
  </code></pre>
  
  <p>I've tried cleaning and rebuilding multiple times as well as deleting bin and obj folders. </p>
  
  <p>I've also removed the nuget packages and had them restored as well as reinstalled them but nothing seems to work. </p>
  
  <p>I've tried updating AppCompat but it won't update, saying it couldn't find versions of Xamarin Forms compatible with the version, even though I have the latest version of Xamarin forms. </p>
  
  <p>All my Android SDKs are up to date </p>
  
  <p>Has anyone else encountered this error? If so, how did you resolve it? </p>
  
  <p>Thank you,</p>
