NEsper :: Open Source ESP/CEP Engine for .NET
In the MIX of recent product announcements, I almost forgot mentioning another cool thing that has finally arrived in the .NET world. No, I'm not talking about Silverlight but in my opinion NEsper is as cool as Silverlight and this is looking to change the ESP/CEP development in the .NET world.
To describe NEsper: It is an open source component for developing ESP/CEP applications on the .NET Platform. As with most other successful .NET projects, It is derived from the excellent Esper which is the open source equivalent for Java. For more info, see

If you are lost as to what CEP/ESP is all about here is something to help you.
"Event Stream Processing, or ESP, is a set of technologies designed to assist the construction of event-driven information systems. ESP technologies include event visualization, event databases, event-driven middleware, and event processing languages, or complex event processing (CEP). ESP deals with the task of processing multiple streams of event data with the goal of identifying the meaningful events within those streams, employing techniques such as detection of complex patterns of many events, event correlation and abstraction, event hierarchies, and relationships between events such as causality, membership, and timing, and event-driven processes.
ESP enables applications such as algorithmic trading in financial services, RFID event processing applications, fraud detection, process monitoring, and location-based services in telecommunications.Pasted from <http://en.wikipedia.org/wiki/Event_Stream_Processing> "
The wikipedia article is good for introduction and here is a list of other resources that you may find useful.
