    copied!<p>I'm getting a very strange error when I try to run svcutil.exe on a WCF service.</p> <blockquote> <p>"OperationBehaviorAttribute can only go on the service class"</p> <p>[InvalidOperationException]: OperationBehaviorAttribute can only go on the service class, it cannot be put on the ServiceContract interface. Method 'EditProduct' on type 'IProductWCF' violates this."</p> </blockquote> <p>I have pasted my code below and if anybody can shed any light on this, I'd really appreciate it.</p> <p>I should point out that it works on every method except "EditOpportunityProductTypes"</p> <p>My Interface:</p> <pre><code>namespace ProductWCF { [ServiceContract] public interface IProductWCF { [OperationContract] string SayHello(AppointmentFeedback objAppointmentFeedback); [OperationContract] Boolean CreateAppointmentFeedback(AppointmentFeedback objAppointmentFeedback); [OperationContract] List&lt;ExpiringContractType&gt; GetOpportunityProductTypes(int opportunityId); [OperationBehavior] Boolean EditOpportunityProductTypes(List&lt;ExpiringContractType&gt; lstExpiringContractTypes, int opportunityId); } } </code></pre> <p>My Service:</p> <pre><code>namespace ProductWCF { public class Service : IProductWCF { [OperationBehavior] public string SayHello(AppointmentFeedback objAppointmentFeedback) { return objAppointmentFeedback.Notes; } [OperationBehavior] public Boolean CreateAppointmentFeedback(AppointmentFeedback objAppointmentFeedback) { ProductData.CRM.Objects.AppointmentFeedback objNewAppointmentFeedback = new AppointmentFeedback(); if (objNewAppointmentFeedback.Insert(objAppointmentFeedback.AppointmentId, objAppointmentFeedback.StarId, objAppointmentFeedback.AppointmentStatusId, objAppointmentFeedback.Notes, objAppointmentFeedback.Creator, objAppointmentFeedback.AttendeeName) &gt; 0) return true; else return false; } [OperationBehavior] public List&lt;ExpiringContractType&gt; GetOpportunityProductTypes(int opportunityId) { return OpportunityProductTypeMethods.GetOpportunityConnectionTypes(opportunityId); } [OperationBehavior] public Boolean EditOpportunityProductTypes(List&lt;ExpiringContractType&gt; lstExpiringContractTypes, int opportunityId) { return ProductData.CRM.Objects.OpportunityProductTypeMethods.UpdateOpportunityConnectionTypes(lstExpiringContractTypes, opportunityId); } } } </code></pre>
