Broken doc : Example code inclusion fail to rended in the doc

Hi, we are looking for advanced feature of sharing documents and the doc is broken.
It shows :
Unresolved include directive in modules/ROOT/pages/_partials/howto/how-to-use-xattrs-for-access-grants.adoc - include::example$/code/csharp/cbsSdkUserXattrKeySol/cbsSdkUserXattrKeyProj/Program.cs[]

Could you please fix it ?
