I'm a huge fan of Kevin's framework and by no means is this a put down to his fantastic work.

I've worked with previous version of his framework for FoxPro since 1997 and have some (not as extensive as the MM MVP's) but enough to recognize the scalable potential.

That said, the company I'm currently working with is using Enterprise Library from Microsoft. This was a joint venture between Avadante and Microsoft. The Application Framework is pretty empresive and has some real, real cool stuff in it. Kevin's work is fabulous but Enterprise Library blew my socks off.

I can definately give you more on comparing the two but I suggest you download the videos located on my dicussion forum and judge it for yourself. The videos are from a presentation at Inland Empire's .NET User Group. Hisham Baz presented the meeting, he's one of the 6 Architects that was involved in the development of the framework. You can check them out at http://www.dandyvibe.com - look for the Enterprise Library Forum and check under the General Discussion Topic for the Videos.

If I had to choose between either one of these two I would literally be torn between them. They are both outstanding frameworks but both have their strangths and weaknesses.
