XDocument doc = new XDocument(  
    new XDeclaration("1.0", "utf-8", "yes"),  
    new XComment("This is a comment"),  
    new XElement("Root", "content")  
);  
doc.Save("Root.xml");  

Console.WriteLine(File.ReadAllText("Root.xml"));  

Dim doc As XDocument = _   
        <?xml version="1.0" encoding="utf-8" standalone="yes"?>  
            <!--This is a comment-->  
            <Root>content</Root>  

doc.Save("Root.xml")  

Console.WriteLine(File.ReadAllText("Root.xml"))
