How to get short description from BlogEngine.net RSS feed

Question

I want to create a start page similar in Visual Studio 2010 from a BlogEngine.net blog feed. Specifically, what I want to achieve is that each article from the feed will:

• have a title.
• have a short description.
• link to the full article when the title is clicked.

The short description will not the same as the article text, which is what I am having problems achieving. What's the best way to add a short description to the feed that differs from the main article's text?

An example of the Visual Studio 2010 start page feed from http://go.microsoft.com/fwlink/?linkid=84795&clcid=409 is below.

    <item>
        <guid isPermaLink="false">0c4d4497-4545-4531-b69a-4b2f499eeda1</guid>
        <link>http://services.social.microsoft.com/feeds/FeedItem?feedId=dae624ea-2aba-4282-a4d7-83a3579c9d07&amp;amp;itemId=0c4d4497-4545-4531-b69a-4b2f499eeda1&amp;amp;title=Computing+a+Cartesian+Product+with+LINQ&amp;amp;uri=http%3a%2f%2fblogs.msdn.com%2fb%2fericlippert%2farchive%2f2010%2f06%2f28%2fcomputing-a-cartesian-product-with-linq.aspx&amp;amp;k=vc%2fxe%2fiUoPj%2fZwB3S6bGGaKf1GQUNuFaof%2fweLBsoIg%3d&lt;/link&gt;
