Exclude files from styleCop analysis does not work

I set in the project file the

    <Compile Include="Directory\File.cs">

               <ExcludeFromStyleCop>true</ExcludeFromStyleCop>

    </Compile>

To tell the tool to exclude the file from the analysis, but still in the output there are messages for errors/warnings in this file …

What is wrong with this approach?
