The DicomConnection is the replacement in the .NET_Version for what was the DicomAssociation in the COM_Version the main difference being that it 'only represents a single association, giving less ambiguity when properties such as RemoteIP etc. are accessed.

There is still though a need to link the 2 associations used when C-MOVE is used, and this is now done using the RequestingQuery property of the DicomAssociation, which for C-MOVE references the QueryReceivedArgs which in turn has an Association property which represents the incoming association over which the C-MOVE request was received. This is important, as it allows the C-MOVE SCU to receive status updates, including NumberRemaining, NumberCompleted etc.
