  Below is my code:

   using(OrganizationServiceProxy _serviceProxy = new OrganizationServiceProxy(oUri,null,lclClientCredentials,null))
                      {
  
                      RetrieveEntityRequest entityRequest = new RetrieveEntityRequest
                      {
                          EntityFilters = EntityFilters.Attributes,
                          LogicalName = "contact",
  
                          // Retrieve only the currently published changes, ignoring the changes 
                          // that have not been published.
                          //RetrieveAsIfPublished = false
                      };
                      RetrieveEntityResponse entityResponse = (RetrieveEntityResponse)_serviceProxy.Execute(entityRequest);
                      Console.WriteLine("Retrieved the contact entity.");
  
                      // Get the entity from the response.
                      EntityMetadata contactEntity = entityResponse.EntityMetadata;
  
                      // Enable document management for the retrieved entity.
                      contactEntity.IsDocumentManagementEnabled = true;
  
                      // Create an update request.                    
                      UpdateEntityRequest updateRequest = new UpdateEntityRequest
                      {
                          Entity = contactEntity                        
                      };
                      _serviceProxy.Execute(updateRequest);

  
  

  Can anyone please help me here, as I am not getting any clue from exception details.
