title: VS2017 Item Template not showing up in Xamarin project
body: <p>I created a new VS2017 project template because the C# 'Class' template for Xamarin.Android adds way too much usings for my tastes. Here's the <code>.vstemplate</code> file:</p>
  
  <pre><code>&lt;VSTemplate Version="3.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="Item"&gt;
    &lt;TemplateData&gt;
      &lt;DefaultName&gt;Class.cs&lt;/DefaultName&gt;
      &lt;Name&gt;Class&lt;/Name&gt;
      &lt;Description&gt;An unfancy C# class.&lt;/Description&gt;
      &lt;ProjectType&gt;CSharp&lt;/ProjectType&gt;
      &lt;SortOrder&gt;10&lt;/SortOrder&gt;
      &lt;Icon&gt;__TemplateIcon.ico&lt;/Icon&gt;
    &lt;/TemplateData&gt;
    &lt;TemplateContent&gt;
      &lt;References /&gt;
      &lt;ProjectItem SubType="Code" TargetFileName="$fileinputname$.cs" ReplaceParameters="true"&gt;Class.cs&lt;/ProjectItem&gt;
    &lt;/TemplateContent&gt;
  &lt;/VSTemplate&gt;
  </code></pre>
  
  <p>I can't figure out why, but this item template won't show up in my Xamarin.Android project. However, the template does show up when I create a new .NET Core/Framework project and click <strong>Add > New Item</strong>.</p>
  
  <p>Any clue what's causing this? I've been staring at MSDN/StackOverflow questions for half an hour but none of them seem to help with this.</p>
  
  <p>I'm using the latest stable build of VS2017, which I think is 15.2.</p>
