Hi!
I've encountered a rather strange problem with my OrganizationServiceProxy object.
I have a Windows Service which reads records from at data warehouse, and pushes them to an MSCRM Online instance.
The service does the following:
1) Establishes the connection
2) Retrieves the metadata information from CRM Online, and builds the entities based on the metadata
3) Maps columns between the data warehouse and CRM
4) Pushes the data using ExecuteMultiple
The strange thing is that the service breaks on a RetrieveMultiple - query:
ERROR 2014-01-30 09:02:12,238 614677ms Logger Run - System.ObjectDisposedException: Cannot access a disposed object.Object name: 'System.ServiceModel.Security.TransportSecurityProtocol'.

Before this error, the service has completed several calls to the organizationserviceproxy in order to retrieve the metadata. It occurs on the exact same place.
Running the service in Test using the same MS CRM online instance does not cause the same problems
The OrganizationServiceProxy is accessed from a property:
internal static OrganizationServiceProxy Proxy { get { if (_proxy == null) { _proxy = Connection.GetProxy(); } return _proxy; } }
public static OrganizationServiceProxy GetProxy() { IServiceManagement<IDiscoveryService> serviceManagement = ServiceConfigurationFactory.CreateManagement<IDiscoveryService>(new Uri(Properties.DiscoveryServiceAddress)); AuthenticationProviderType endpointType = serviceManagement.AuthenticationType; AuthenticationCredentials authCredentials = GetCredentials(endpointType); String organizationUri = String.Empty; using (DiscoveryServiceProxy discoveryProxy = GetProxy<IDiscoveryService, DiscoveryServiceProxy>(serviceManagement, authCredentials)) { if (discoveryProxy != null) { OrganizationDetailCollection orgs = DiscoverOrganizations(discoveryProxy); organizationUri = FindOrganization(Properties.OrganizationName, orgs.ToArray()).Endpoints[EndpointType.OrganizationService]; } } if (!String.IsNullOrWhiteSpace(organizationUri)) { IServiceManagement<IOrganizationService> orgServiceManagement =ServiceConfigurationFactory.CreateManagement<IOrganizationService>(new Uri(organizationUri)); AuthenticationCredentials credentials = GetCredentials(endpointType); //Set OrganizationServiceProxy return GetProxy<IOrganizationService, OrganizationServiceProxy>(orgServiceManagement, credentials); } throw new Exception("Failed to establish OrganizationServiceProxy"); }
This method causes the error to be thrown:
internal static Dictionary<Guid, Entity> GetAllRecords(string entityName)
{
//Get Attribute Typecode of primaryKeyColumn
//AttributeTypeCode attributeTypeCode = GetAttributeTypeCode(entityName, primaryKeyColumn);
int fetchCount = 5000;
int pageNumber = 1;
var results = new Dictionary<Guid, Entity>();
QueryExpression pagequery = new QueryExpression();
pagequery.EntityName = entityName;
pagequery.ColumnSet.AllColumns = true; //Not exactly best performance, creating an awfully big soap envelope. Possible improvement. Add values for primarykey name and type in mappings.xml
pagequery.PageInfo = new PagingInfo();
pagequery.PageInfo.Count = fetchCount;
pagequery.PageInfo.PageNumber = pageNumber;
pagequery.PageInfo.PagingCookie = null;
while (true)
{
// Retrieve the page.
EntityCollection ec = Properties.Proxy.RetrieveMultiple(pagequery);
if (ec.Entities != null)
{
// Retrieve all records from the result set.
foreach (Entity entity in ec.Entities)
{
//Add to results dictionary
results.Add(entity.Id, entity);
}
}
// Check for more records, if it returns true.
if (ec.MoreRecords)
{
pagequery.PageInfo.PageNumber++;
pagequery.PageInfo.PagingCookie = ec.PagingCookie;
}
else
{
break;
}
}
return results;
}I use the exact same configuration in Test as in production. I use the same database, and the same CRM Online organization. The only difference is that I simulate the Windows Service run using a Unit Test in Test mode, while I run it as an actual windows
service in production.
If anyone have any suggestions on where to look in order to solve this issue I would be most grateful
