Stylecop still checks generated file even I have the setting to skip it

I have a class library project with stylecop enabled, the rules skip all generated files like I have shown in screenshot here.

But when I start to add a new workflow activity (Activity1.xaml) I got error messages from Stylecop
  • Warning as Error: Missing XML comment for publicly visible type or member 'MyProject.Activity1.Activity1()' C:\MyProject\Trunk\MyProject\obj\Debug\Activity1.g.cs
  • Missing XML comment for publicly visible type or member 'MyProject.Activity1' C:\MyProject\Trunk\MyProject\obj\Debug\Activity1.g.cs
Can somebody explain to me how it happened?
