console app application insight logging is not working

[ruonan0509]

since Application Insights “Instrumentation Keys” are Sunsetting on March 31, 2025, i am trying to convert current applicationInsights config from Instrumentation Key to Connection String

current startup:

public void ConfigureServices(IServiceCollection services) => services
.AddApplicationInsightsTelemetryWorkerService("00000000-0000-0000-0000-000000000000");

changed to

public void ConfigureServices(IServiceCollection services) => services
.AddApplicationInsightsTelemetryWorkerService(options => options.ConnectionString = "InstrumentationKey="00000000-0000-0000-0000-000000000000");

but the new code is not logging anything to the same AI transaction logging. am I missing anything? thanks!

Make sure you copy the ConnectionString verbatim from your Application Insights resource.
If that's not working, you can collect SDK logs to identify any errors within the SDK

thank you @TimothyMothra getting back to me
here is my AI

the connection string is very long, shall i copy the whole thing or just InstrumentationKey=xxx part?
and also where i can find the SDK logs? thank you!

Yes, full string. The SDK needs those Endpoint values.

Self diagnostics would be the easiest way to collect internal logs: https://github.com/microsoft/ApplicationInsights-dotnet/tree/main/troubleshooting/ETW#self-diagnostics
