History

The project was founded by Hamilton Verissimo de Oliveira (aka "Hammett"), who was a member of the

and the

projects. Keenly interested in the development of an

, and the Castle Project eventually expanded its mission "to provide a simple set of tools to speed up the development of common enterprise and web applications while promoting good architecture". The Castle Project continues to gain acceptance and mind-share from the .NET community, including recognition from Microsoft thought leaders as a framework to assist with building "robust, extensible, working software". In 2006, Hammett started his own company to offer commercial support for the Castle Project and for the applications developed using the framework. In August 2008, he joined Microsoft as a Program Manager on the MEF team. On October 31, 2008, Hammett announced on his blog that the Castle Project had been split, and subsequently all subprojects would be maintained and released independently. The first project to be released after the split was DynamicProxy, on May 4, 2009.
