please, me list of names! wrong?

thank you.

you're ignoring this:

xmlns="http://schemas.microsoft.com/developer/msbuild/2003" 

that sets default namespace descendants. want:

xnamespace ns = "http://schemas.microsoft.com/developer/msbuild/2003"; var elem = doc.descendants(ns + "project")                .where(t => t.attribute("toolsversion")!=null)               .elements(ns + "itemgroup")               .elements(ns + "reference")               .where(r => r.attribute("include") != null);
