Today I stumbled over the following: There are cirular references in the .NET Framework. For example, System.Xml references System.Configuration and System.Configuration references System.Xml. See the following: http://www.stephan-brenner.com/blog/wp-content/uploads/2007/05/circularreferences.png

There are a lot of that artifacts in the framework and I'm wondering why? And how does Microsoft manage to build this?
