public static long GetUniqueId()  
{  
   if (_instance != null)  
   {  
      return _instance.NextId("importID");  
   }  
   var storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));  
   IOptimisticDataStore blobDataStore = new BlobOptimisticDataStore(storageAccount,  AzureCloudStorageServices.GetStorageContainerName());  
   _instance = new UniqueIdGenerator(blobDataStore);  
   return _instance.NextId("importID");  
}
