Returning PDFs from an ASP.NET MVC action

This feature is based on a post from Bill Barry, “Using Spark to render PDFs,” to the Spark discussion group. It’s based on iTextSharp, a port of the iText Java PDF library. It seemed like such a useful twist on the view engine, and so applicable to web sites, that I integrated what Bill had done into the Spark project and added a PdfViewResult action result for the ASP.NET MVC library.
