One cool new feature available in Visual Studio 2005 is the ability to take advantage of Intellisense statement completion in the Source view of an ASP.NET Web Form. In addition, Visual Studio 2005 provides validation of your markup.
Both of these features are driven by XSD schemas that are installed with Visual Studio 2005, so you can change the schema on the fly, to test your markup for compatibility with a variety of browsers.
Thanks to Mikhail Arkhipov from the ASP.NET team, I was able to put together a demonstration of this feature, including creating and using your own custom XSD schema to drive Intellisense and validation.
In this DevNugget, .net Developer Evangelist G. Andrew Duthie (aka .net DEvHammer), shows you how you can quickly and easily create and register a custom XSD schema that allows get Intellisense and validation of your schema within the Web Form source view window.
