Look at the root namespace; you'll have to include an xml-namespace manager and use queries like "//x:ItemGroup", where "x" is your designated alias for the root namespace. And pass the manager into the query. For example:

        doc.Load("my.csproj");

        XmlNamespaceManager mgr = new XmlNamespaceManager(doc.NameTable);
        mgr.AddNamespace("foo", doc.DocumentElement.NamespaceURI);
        XmlNode firstCompile = doc.SelectSingleNode("//foo:Compile", mgr);
