No code coverage generated from windows service - using Microsoft.CodeCoverage.Console

[Manishd79]

Hello,

We have a windows service (exe) based upon many static libraries - native code. We are using Microsoft.CodeCoverage.Console to instrument statically the service exe. This instrumented service and other dlls are deployed on machine using our installer product. The service (instrumented) runs under "Local System" account and looks good.

We are relying on our E2E tests which perform many actions where service code (via static libs) definitely is touched, even we confirmed our product's events in the event viewer. However, the code coverage collection action is yielding no coverage for the service. I am putting a sample command as how I tried to run code coverage manually

Microsoft.CodeCoverage.Console collect --output C:\coveragefile.coverage --session-id --server-mode
Perform stop/start of service
Perform certain action for few static libs linked to service
Microsoft.CodeCoverage.Console collect shutdown

The same 'session guid' was used to instrument during compilation time.

The coveragefile.coverage does indicate our service as one of the instrumented exe but nothing reported covered:

Appreciate some help/pointers as how to unblock here.

I think the issue is that service is running under "Local System" but Microsoft.CodeCoverage.Console.exe is running under "User". Can you please try to run service under the same user which is running Microsoft.CodeCoverage.Console.exe? Also, can you please specify what kind of service this is? IIS?
