FxCop - Use properties where appropriate

Question

I have interface in service layer with several methods starting with Get and FxCop's Use properties where appropriate rule complains that I should consider using properties instead.

I tried to use SuppressMessageAttribute but when it's defined on interface it has no effect on member methods. Do I need to put SuppressMessageAttribute to every method or is there a way to suppress CA1024 for a whole type?

[SuppressMessage("Microsoft.Design", "CA1024:UsePropertiesWhereAppropriate"]
public interface IProjectService
{
    // Information and statistics about projects
    IList<ProjectInfo> GetProjects();
    ProjectsDashboard GetProjectsDashboard();

    // Project's settings
    ProjectSettings GetProjectSettings(Guid id);

    void SaveProjectSettings(ProjectSettings settings);
}

Answer 1

You will have to add the attribute for each method.
