Question

I've created a .Net 6 Isolated HttpTriggered function in Visual Studio 2022

I'm trying to get the TelemetryConfiguration injected, and based on other issues logged and docs this should NOT be null once my local.settings.json has a value for APPINSIGHTS_INSTRUMENTATIONKEY

However, that isn't the case when running locally.

Is there a new way to access it in .Net 6 isolated? Cause this works just fine in my .Net 3.1 functions.

Thanks for your time!

@willyt150,

The documentation is wrong.
The right way to inject TelemetryConfiguration is using IOptions interface, like this:

IOptions

thanks @lommez

your example is missing the actual implementation, but I'm familiar with the IOptions, so you pointed me in the correct direction. Thank you again!

so @v-bbalaiagar my issue has been solved, but the docs just need to be updated calling out how to properly retrieve the injected telemetry configuration.
