Trying to understand the ColdFusion 8 - Net integration

All, I'm just starting to learn .Net.  I'm trying to grasp the concept of what .Net assemblies are.  Would it be fair to say that they are like CFCs?  I'm trying to get a comparible CF analogy. I'm assuming you can't access to lines of logic within an .Net Web page, but that these .Net assemblies are compiled dlls or something.  I'm trying to understand exactly what I can grab from a .Net application. A layman's explanation would be so appreciated.  My boss, who is a director of Marketing has talked about switching to .Net because it what some Web agencies are saying we should be using. http://www.brooks-bilson.com/blogs/rob/index.cfm/2006/10/24/Adobe-MAX-2006-Session--ColdFusion-Net-Integration Thanks D
