Hi! I saw your instruction on how to make setup a RSS feed on http://sleslie.me/2014/rss-feed-with-razor-in-umbraco/

Everything worked like a charm, thumbs up, but I noticed a litte bug your instructions where you say
Create a partial view macro called 'Razor', create Macro at same time.
I believe it should say RSS here, not 'Razor'

Why not write this line more simple? :)

@Html.Raw("<link>")@[email protected](release.Url)@Html.Raw("</link>")

so instead this:

<link>@(siteURL + release.Url)</link>

or

<link>@(String.Format("{0}{1}", siteURL, release.Url))</link>
