Use the AlternateView class to specify copies of an e-mail message in different formats. For example, if you send a message in HTML, you might also want provide a plain text version in case some of the recipients use e-mail readers that cannot display HTML content.

This class has two properties LinkedResources and BaseUri that are used to resolve URLs within the content of the email. LinkedResources is a collection of LinkedResource objects. When rendered, URLs within the e-mail's content are first matched against the URLs in the ContentLink of each LinkedResource object in the LinkedResources collection, and resolved. BaseUri is used by the mail reader to resolve relative URLs within the body, and also to resolve relative ContentLink URLs, in the LinkedResources collection.
