My previous article showed how to use a custom ActionResult and the classes within WCF to generate an RSS feed. There are no similar classes to help build a valid Google Site Map for an ASP.NET MVC application. So here's how your can build your own.

When I looked at producing RSS Feeds in ASP.NET MVC before, I used the ContentResult method to return XML. Best Practice suggests that you should create a new ActionResult if required. So this article looks at creating an RssResult, and a different way to generate the feed itself.

Following on from the recent spate of extensions methods I've posted, here's another I use to convert URLs and email addresses into links within HTML. You may want to restrict users from submitting HTML tags via forms in your application, which means that URLs and email addresses that they submit appear as plain text unless they are subjected to some kind of processing.

A common question in the forums is how to highlight key words found in search results. Here's an extension method that does that, both for partial matches, or whole word matches.

The jQuery Cycle plug-in is most often used for creating image slide shows. However, it's just as easy to use to create a news scroller from a ListView. Here, I look a doing just that. I also look at an alternative jQuery plug-in (NewsTicker) that gives the effect of the classic BBC News Ticker.

People often post questions to the forums at www.asp.net asking what they need to learn to become an accomplished ASP.NET Web Developer. Answers vary, but tend to focus on learning the framework and a bit of SQL, along with finding your way around Visual Web Developer, or if you can afford it, Visual Studio. My answer tends to consist of the same list of items:

The MVC 2.0 Framework was finally RTM'd on March 11th 2010, so I took the opportunity to update my Contact Manager application with some of its new features. While the focus of this article is validating the Model using DataAnnotations, I also touch on one or two other new features in the latest release.

It seems that the whole world (and Margate) is having its say on which is better - MVC or Web Forms. Scott Guthrie posted his views on technical debates in general, and then contributed his thoughts on MVC v. Web Forms. Ian Cooper has an interesting contribution to make to the debate too. Rob Conery (formerly of Microsoft) posted probably the most linked to opinion on the matter. (There - I've just added another link...) A lot of other blog posts around scream that MVC is better because its better. One even tries to posit the notion that some kind of score card approach can help you decide.

Pretty much every sample application that illustrates ASP.NET MVC uses Linq To SQL or the Entity Framework as the data access method. I've seen a number of questions posted to the forums at www.asp.net asking if there are any alternatives, and indeed there are. This article will look at using plain ADO.NET within a data access layer to provide dynamic content to a typical small CRUD application.

The most recent addition to my Cheat Sheets features details of all the Exceptions that can be found in the most commonly used assemblies within ASP.NET development. Compiling this information was an interesting challenge. I could have simply copy-pasted from MSDN, but that would have been extremely tedious. Instead, I ended up with a blend of Linq to XML, Reflection, a dash of Regex and the Global Assembly Cache Tool - gacutil.exe. Here's the full story.

Here's a list of Exceptions that can be found in the assemblies which are most commonly used in ASP.NET development. Ideally, you should be as specific as possible when catching or throwing Exceptions. The more specific you are, the less work the CLR has to do in locating the appropriate catch block, and the more informative your error messages are, which should help speed up identifying the source of any problems.

A frequent requirement for ASP.NET developers is to schedule tasks at regular intervals. This can include site maintenance tasks, like cleaning up old files, emailing newsletters on a schedule etc. This article examines one easy option for managing tasks like these without having to configure external tools, and discusses a couple of alternatives.
