I could have used it a couple weeks ago while debugging a concurrency related issue for a WCF service - it would have significantly reduced the amount of thinking I had to do. While doing some performance testing of a business process that spanned several WCF services, I ran into a concurrency related issue. We had the InstanceContextMode set at PerCall but still had the problem. Why? The service was also getting some information for processing from the database. Changing to InstanceContextMode to Single was the workaround until we could make the real fix since we don't want a singleton running for this service in production. Best, Mike Hey Thomas,
