Hi,
we recently upgraded from CRM 2015 to CRM 2016 on premise and one plugin, which was working fine in CRM 2015, is no longer working in CRM 2016.
I already changed the SDK dlls in the references of the plugin from the 2015 ones to the new 2016 dlls and updated the plugin assembly, but still it doesn't work.
It always throws the error:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=8.0.0.0, Culture=neutral, PublicKeyToken=xxx]]: Unexpected exception from plug-in (Execute): CrmVSSolution1.Plugins.PostZuwendungCreate: System.ServiceModel.CommunicationObjectFaultedException: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.Detail:

Any idea, what could be wrong?
thx in advance Thomas
