When updating a custom entity in CRM 2011, I receive the following error on service.update(entity):
"Can not create plug-in"
"Can not create instance of a plug-in."
I am only updating the fields I need.
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Can not create instance of a plug-in.

<OrganizationServiceFault xmlns:i="www.w3.org/.../XMLSchema-instance" xmlns="schemas.microsoft.com/.../Contracts">
<ErrorCode>-2147180031</ErrorCode>
I have not been able to resolve this. Please help.
