But the code sample just shows us that the callout is actually a call to another service. so does any normal callout will release the lock such as calling into another normal .net methods rather than calling into another service operation?

Calling into a method on a type does not unlock the service object. If you need this kind of behavior, then you can set the ConcurrencyMode to ConcurrencyMode.Multiple and lock state yourself.

Happy to help.

IRT MSDN documentation, I agree that we should add another sentence or two that clarify the point. I'll certainly pass that feedback on.

As a result of your feedback, new verbiage that is more precise will/should appear in the .NET Framework 3.5 documentation.

These changes go through an approval process, but I don't see any roadblocks.

Hey Justin,

I thought, you may be able to help me with this.
We have setup a SCF service which runs with a ConcurrencyMode.Single
Till a few days back we were only a few connecting to that service. Now there are more clients connecting to this service and service has stopped accepting the clients.
I tried changing the concurrency modes to different values and nothing helped.
We are hosting this service into a Windows NT Service.

Let me know if there is something that I need to set on the service to handle more concurrent calls or its altogether a different problem?

Thanks
Suhas
