Providing Content as an RSS Feed

We will create a mechanism that will allow users to point their RSS aggregator to a page and retrieve the postings that have been updated within a set number of days. An RSS aggregator is a program that can retrieve items from one or more RSS feeds and display the items in a readable form.

Creating the RSS Feed

For the purposes of this example, we will create a new web form in the Tropical Green sample site.

Let’s jump right into the code:

1. 1. Launch the Tropical Green solution in Visual Studio .NET.

2. 2. Create a new folder to store our RSS web form by right-clicking on the TropicalGreen project and selecting Add | New Folder. Name the new folder UtilityPages.

3. 3. Create a new web form in the UtilityPages folder by right-clicking on UtilityPages and selecting Add | Add New Web Form.

4. 4. Name the item rss.aspx and click Open.

5. 5. We should now have a blank web form created and opened in Design view.

The web form we are creating will return XML and not HTML...
