Vista - Visual Studio seems to kill singleton instance of a WinFX service

I am using a service that is configured to run as a singleton instance,
hosted in IIS.
Whenever I start the same client out of Visual Studio I can see that the
instance of the service is reinitalized. I could also see it by attaching a
debugger, because I hit the constructor every time the client connects.

When I start the client directly e.g. out of Windows Explorer I get the
original instance.

Has anyone observed a similar behaviour concerning singleton services?

Did you check that InstanceID back, that always the same in that case at
least on my computer

Stefan,

Do you see the same behavior when using the Instancing Sample? You can find
this sample under WCF Technology Samples/Basic WCF Technology Samples/Service
Samples/Instancing.

Thanks,
