Disable warnings for specific files in Visual Studio

Question

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...

EDIT: Example warnings (there is 1623 warnings for single .pak file)

Warning 498 Attribute ' C:\Users\Dominik\Projects\slidessync\SlidesSync\SlidesSync\cef.pak  41526   1   SlidesDrive.Windows

Answer 1

Late, but the most obvious is to place in the top of the file

#pragma warning disable warning-list
