title: Disable warnings for specific files in Visual Studio
body: <p>I have some files in my C# WPF project with Build Action set to Content. But these files don't contain C# code. Unfortunatelly, these files generates a lot of Warnings in Error List. How can I set these non-c# files to be ignored in "VS Warnig Analyzer"? I tried use Exclude from StyleCop, but warnings are still here...</p>
  
  <p>EDIT:
  Example warnings (there is 1623 warnings for single .pak file)</p>
