The Avalon.Net don't have a publically release available yet. In the meantime you can download the current version from avalon-sandbox CVS.
We (the Avalon team members involved in this project) didn't consider Avalon.Net just a port from Java version. The framework already has some differences. The .Net version lives in a totally different world and don't have to deal with problems of the Java world such as the absence of an assembly concept, attributes/metadata etc.
This proposed version was strongly inspired by Excalibur Fortress container because it is the simplest one. Some things like the dependency checking (aka DirectedAcyclicGraphVerifier) could be entirely used in the .Net version.
