I released the 0.5 version of the Nucleo framework yesterday to http://nucleo.codeplex.com.  In it are:

  • General utility components
  • Web helper methods
  • AJAX controls for web forms
  • AJAX controls for MVC
  • A basic MVP framework that will grow in the future
  • Helpers for testing, TDD
  • NUnit assertions, helpers

There are two downloads, one for the source binaries (and documentation), and one for the sample projects.  Let me know what you think of it.
