Answer by mmx for Generating RSS with ASP.Net MVC?

Use WCFSystem.ServiceModel.Syndication namespace for which you need to add System.ServiceMode.Web to your references. That handles the whole thing automatically:

using System.ServiceModel.Syndication;// ...var rss = new SyndicationFeed(...);...var formatter = new Rss20FeedFormatter(rss);formatter.WriteTo(xmlWriter);
