To better support and manage this project, I'm deploying incremental releases for the web controls, which are AJAX enabled. Right now, this release only contains a button control that's fit for the release deployment. PLEASE DO NOT USE ANY OF THE OTHER CONTROLS: you can, but they probably won't work.
The available control is in the Nucleo.Web.ButtonControls namespace, in the Nucleo.Web.WinFX assembly. Documentation will be available on the site. Note the use of the AJAX Control Toolkit; I will be eventually dropping this, but for now it's supported until I can redo some of the other code.
