title: How do I avoid invalid characters in XML files using OctoPack during VSTS builds?
body: <p>I am seeing these errors during builds.</p>
  
  <pre><code>C:\Program Files (x86)\Microsoft WCF Data Services\5.6.4\bin\.NETFramework\Microsoft.Data.Services.Client.xml' contains invalid characters.
  C:\Program Files (x86)\Microsoft WCF Data Services\5.6.4\bin\.NETFramework\Microsoft.Data.OData.xml' contains invalid characters
  C:\Program Files (x86)\Microsoft WCF Data Services\5.6.4\bin\.NETFramework\Microsoft.Data.Edm.xml' contains invalid characters.
  C:\Program Files (x86)\Microsoft WCF Data Services\5.6.4\bin\.NETFramework\System.Spatial.xml' contains invalid characters.
  </code></pre>
  
  <p>I dont get them locally when I run MsBuild with the same arguements, and I can even run MSBuild on the private build agent just fine too.</p>
  
  <p>I have other projects using OctoPack just fine, and using these packages. I am going to double check them very carefully because the other ones work just fine.</p>
