I’ve written a quick example of a Google Gadget. There is nothing really special about it as its hosted in an IFrame so that I could get at local assets (like my RSS feed) to the Gadget. It isn’t a lot to look at, but if anyone is interested in the process or want to add it to their iGoogle page, feel free. Here’s the Gadget in action:
UPDATE: The BrowserHttpWebRequest doesn’t look like it works right in Firefox (though the control does render). I’ll have to look into it, but I think it may be a bug (since I am using Silverlight 1.1 in this case).
ANOTHER UPDATE: Should be working for Firefox now. I found an oddity I am still trying to work out.
