I am new to Azure Service Fabric and C# and I'm looking for an equivalent to "kubectl logs -f" in sfctl. Is there any other way to view the stdout log of a service?
It's not as easy as with Kubernetes, but the recommended approach is:
In your case, you'd use App Insights to see Service traces and logs. Make sure to enable 'developer mode' locally, to decrease the time it takes for logs to show up.
