I'm creating an application to try out some Azure features and the setup is Web API plus a Blazor application hosted in two separate App Services in a single App Service plan.
I was setting up Application Insights and I wasn't sure AddApplicationInsightsTelemetry is actually needed or not. Turning on Application Insights in the portal seems sufficient, but AI is giving me confusing suggestions as to whether calling AddApplicationInsightsTelemetry in Program.cs is actually need.
Any thoughts?
