How to deserialize xml to List<T>

I have object of some type, let's say Foo, looking like: 

public class Foo
{
    [XmlElement("id")]
    public string Id {get; set;}

    [XmlElement("name")]
    public string Name {get; set;}
}

Also i have xml:

<root>
    <foo>
        <id>1</id>
        <name>name_1</name>
    </foo>
    <foo>
        <id>2</id>
        <name>name_2</name>
    </foo>
</root>

What am i doing wrong trying to deserialize that xml to List using XmlDeserializer with following code?

var list = new List<Foo>();
var serializer = new XmlSerializer(typeof(List<Foo>));
using (var reader = new StringReader(xml))
{
    list = (List<Foo>)serializer.Deserialize(reader); //error here
}

Getting exception:

System.InvalidOperationException

<root xmlns=''> unexprected .

The root element does not match. There are ways to pass it into the constructor of XmlSerializer, but IMO your best bet is to create a wrapper class:

[XmlRoot("root")]
public class FooWrapper {
    [XmlElement("foo")]
    public List<Foo> Items {get;set;}
}

And pass this type to XmlSerializer.
