What are Components in C#?

The components creation and usage in C# is much more simple than earlier technologies like C++, ATL COM. As we know a Components represent all kinds of elements that pertain to the piecing together of software applications. Among other things, they may be simple files, or libraries loaded dynamically.

A component is a class with cleanup and containment. A component can be hosted in a container, and has the ability to query and get services from its container. Containment is logical and does not have to be visual. These components can be deployed in middle tier container as business components. Example database components deployed in middle tier.
