Enso C# extension framework http://www.shafqatahmed.com/2007/12/in-love-with--1.html

http://sourceforge.net/projects/ensoextension Yet another C# Enso extension framework based on previous one. The project includes a server application which communicates with Enso and serves as a container for pluggable modules (pluggable extensions) which actually implement commands. An extension does not need to support a connection to Enso itself and a large number of pluggable extensions can communicate with Enso through a single connection which is supported by the container. The project includes a sample extensible web search extension. It allows of adding new search providers just writing a search engine description in the simple XML-based OpenSearch format.

ENSO+ is "ready to use" software built up on previous two extensions and closed source Enso product. It contains many new commands and ideas. See video at http://www.f4cio.in.rs/ensoplus.aspx
