How to Sync a C# Application in-memory object

Question

I have a WCF service to be load balanced with NLB (Windows Network Load Balancer). So I need a Dictionary object to be synced across all the instances of the WCF service.

What is the best possible way to do this?

Answer 1

WCF Services are by nature, stateless. You can turn on classic mode and use session, but session will have to be stored in the database. You can share in-memory objects across servers.
