C# Circular Dependancy

Question

Hi all Design question I have three library projects A B and C. Project A - error logging class Project B - properties class with static methods Project C - eventing class with static methods Unfortunately I want project A to use the properties class B B to use the eventing class C and C to contain an error logger object resulting in a circular dependancy: A > B > C > A How can I get around / redesign this? I'm a bit of a novice and might be missing the obvious but I don't see how I can use an interface as C contains an error logging object it is not passed an error logger as a method parameter. Thanks in advance am so confused!

Here is Example of Four Circular Dependency .. A->B->C->D->A if my answer helps you then check Do you like this answer check box please :) Project A Public Class A Implements C.IA Public Function foo ( ByVal value As C . IB ) As Integer Implements C . IA . foo Return value . bar ( Me ) End Function End Class Project B Public Class B Implements C.IB Public Function bar ( ByVal value As C . IA ) As Integer Implements C . IB . bar Return value . foo ( Me ) End Function End Class Project C Public Interface IA Function foo ( ByVal value As IB ) As Integer End Interface Public Interface IB Function bar ( ByVal value As IA ) As Integer End Interface Project D Sub Main () Dim a As New A . A Dim b As New B . B a . foo ( b ) End Sub
