The book I have on the subject of ASP.Net 2.0 makes a big deal about WebParts. They seem very powerful, and they remind me of DotNetNuke in some visual ways (if there are nothing alike, please forgive my ignorance).
I was just wondering if anyone has used these. I asked some of the Web ppl I know about it, and none of them are very familiar with them. I can certainly see how you could build a very powerful page with them.
