I'm trying to setup Application Insights on my ASP.NET Core 3.1 web application but without success... I installed the version 2.16 of "Microsoft.ApplicationInsights.AspNetCore", then add the following line in the startup.cs file:
services.AddApplicationInsightsTelemetry(_configuration);
Moreover, I added the following section in the appSettings:
"ApplicationInsights": {
"InstrumentationKey": "XXX"
}
When I launch this with Visual Studio, I can see data in Live metrics, however, as soon as I deploy this in the production server with IIS, it just display that the application is off. I tried to put the connection string instead, without luck.
I'm suspecting a proxy issue, however, I have no way to be sure of this and it seems unlikely because I'm using the proxy as well on my local machine where it works.
I put the log level of the application on "Information" and I see nothing related to Application Inisights. I even tried to enable the developer mode, it didn't change anything.
The main issue is that I have no error anywhere, so I don't even know what to search :-)
