I saw Brad did this and thought it was a cool idea, so here goes:

Now to add meta tag and icon on the page...

Part three of the four part series has been posted over on the O'Reilly Network. In this part they discuss design-time integration of custom web controls with the VS.NET IDE. The article is rich with detail and examples and covers an integration feature that I had heard about, but never seen documented: Custom schemas and Visual Studio annotations. Great stuff!

Richard Grimes just posted a message to the DOTNET-CLR list in which he points to a download for a little project he's been working on: Dynamic Forms. Basically it enables declaritive form generation via an XML file. Think of it as XHTML for Windows Forms.

Richard then asks:

"Its been fun to do this, but the question is: what use is it? Can anyone suggest a use for this code?"

Hmmm... that's a good question. I'll have to think a bit more about it, because nothing comes to mind immediately other than "it's cool!". ;)

Update:
Now that the download is working, I checked out the source. Originally, going only by Richard's description, I thought it was actually done via a custom configuration section handler. While that isn't the way it's implemented, it certainly could be. My only suggestion is that the <event> element contents be encoded as CDATA to avoid problems with special XML token characters in the languages that are used to handle events. In the example supplied, Richard doesn't use any of these tokens so it's not a problem.

A couple of people have pointed out in follow ups to the thread that one application for this technology could be skinnable applications.
