Its Object to XML serialization. Not Class to XML.

Have a look at below link for XML Serialization example.
http://support.microsoft.com/kb/815813

And then use XmlDocument to save your XML string to File, as below.

C#

string exaample = "<xml><test></test></xml>";
XmlDocument xdocument = new XmlDocument();
xdocument.LoadXml(exaample);
xdocument.Save("TestXMLFile.xml");

Forget about WPF and MVVM, they are totally irrelevant. Embrace the idea of separation of concerns. And just learn about serialization:
http://en.wikipedia.org/wiki/Serialization[^],
http://msdn.microsoft.com/en-us/library/7ay27kt9%28v=vs.110%29.aspx[^].

Perhaps the most advanced and easiest to use is the serialization based on Data Contract:
http://msdn.microsoft.com/en-us/library/ms733127%28v=vs.110%29.aspx[^].

In my past answers, I tried to explain why is that so:
How can I utilize XML File streamwriter and reader in my form application?[^],
Creating property files...[^].

serialization is nothing with wpf or mvvm (I assume your question is about serialization in general). The following is not the only way, but if you want to serialize an object:

C#

// File: AClass.cs
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;

namespace ConsoleApplication1
{
    [Serializable]
    public class AClass
    {
        public string AProperty { get; set; }

        public void SerializeMe(string intoFile)
        {
            // http://msdn.microsoft.com/en-us/library/vstudio/system.io.streamwriter
            using (var fs = new StreamWriter(intoFile))
            {
                // http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer.aspx
                var ser = new XmlSerializer(typeof(AClass));
                ser.Serialize(fs, this);
            }
        }
        public static AClass Deserialize(string fromFile)
        {
            AClass instance = null;
            // http://msdn.microsoft.com/en-us/library/vstudio/system.io.streamreader
            using (var fs = new StreamReader(fromFile))
            {
                var ser = new XmlSerializer(typeof(AClass));
                instance = (AClass)ser.Deserialize(fs);
            }
            return instance;
        }
    }
}

use it as:

C#

// File: Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Test("test.xml");
        }

        static void Test(string xmlFile)
        {
            AClass a = new AClass() { AProperty = "prop value" };
            a.SerializeMe(xmlFile);

            var b = AClass.Deserialize(xmlFile);
        }
    }
}
