title: Did not find new element in the hierarchy for item
body: <p>I am trying to create a simple page for a Xamarin app but am completely unable to proceed with the most basic of steps. I check out the branch from the project repo, and attempt to add a new file. When I do so (Right clicking on folder, Add-> New Item->Content Page) I get this error:</p>
  
  <p><img src="https://i.imgur.com/qUCHqsV.png" alt="This Error"></p>
  
  <p>It does actually create the .xaml file but not the <code>.xaml.cs</code> file to go with it. I first tried to manually create the cs file and associate it but ran into increasingly mysterious errors. Today I created them outside of VS before booting it up and both files are now present but with the dotted icon instead of a regular one and the cs file is not nested beneath the xaml file.</p>
  
  <p>If I try to open my projitems file inside VS to make the association I am given the error "Specified method is not supported". If I choose to 'Open With', no screen ever pops up allowing me to choose. After this I closed down VS and edited the projitems file in notepad again and linked the xaml and cs file. This looked as though it worked but when I add it to the main <code>TabbedPage</code> with a simple <code>Children.Add(new MyReviews());</code> it is not recognized -> <code>The type or namespace name 'MyReviews' could not be found</code>.</p>
  
  <p>These error happen if I make my own branch based on the master or try to add a new file to the master directly. No one else in the project is having these errors.</p>
  
  <p>The only thing I really did differently from the rest is try to get the emulator working for android which apparently has a lot of compatibility issues and requires older versions of the xamarin plugins. I was not able to do this and ended up uninstalling and reinstalling everything twice since I didn't touch the installer software the first time and everything stuck.</p>
  
  <p>Is anyone able to help me debug these issues or know why I am encountering so many at every turn?</p>
