Three ways to consume Amazon Web services in .NET

There are three ways to consume Amazon Web services in .NET.

1. Using System.Net.WebRequest to get data and System.Xml.XmlTextReader to parse data. This way is recommended by Amazon.com.
2. Using System.Xml.XmlTextReader to get and parse data. I prefer this way. The underlying might be the same as the first way.
3. Getting the WSDL file and generating a proxy. This is the way that Microsoft recommends to consume a Web service.
