In 2010 I convinced my employer, the Epitec Group, to open source our project management software, which we called Epiworx.
This is a rewrite of a previous version which can be found at https://github.com/mattruma/epiworx. In this version I am leveraging dependency injection for the data access layer, real unit testing and move to the Razor view enginer for ASP.NET MVC3.
I can be reached at mattruma@gmail.com or on twitter at http://www.twitter.com/mattruma.
This is a full feature application based on Rockford Lhotka's CSLA framework ... so if you are looking for example of any implement of the CSLA framework, this project would be a good start.
Thanks and looking forward to seeing other developers contributions soon!
