Check for a solution in the Azure portal

For issues in production, please check for a solution to common issues in the Azure portal before opening a bug. In the Azure portal, navigate to your function app, select Diagnose and solve problems from the left, and view relevant dashboards before opening your issue.

When targeting net8.0-windows and the Azure.Identity package is installed (though not directly referenced), my http trigger fails to load. If I change the target to net8.0, it works. OR, if I remove the Azure.Identity package, it works. But with both of those it fails. Also, when I run it locally, it works. I wasn't sure if I should post this here or on the azure sdk repo, but since it works locally but not when deployed, I figured I would start here. I created a basic repo to reproduce the issue - see below for details.

Investigative information

These are from the test function I created to reproduce the problem:

  • Timestamp: 2024-04-30T18:39:46.389 (issue is ongoing)
  • Function App version: 4.33.1.22394
  • Function App name: function-start-failure
  • Function name(s) (as appropriate): Function1
  • Invocation ID: (Function is unable to load)
  • Region: Central US

Repro steps

  1. Create new "isolated worker" net8.0-windows function app
  2. Add an http trigger
  3. Add Azure.Identity package
  4. Deploy it (it works locally)

Expected behavior

Http trigger loads.

Actual behavior

Http trigger fails to load.

Known workarounds

Avoid using Azure.Identity. Change to net8.0 (not an option for me but does fix it)

Related information

Here is an example repo that reproduces the issue: https://github.com/Anchora-Solutions/FunctionStartFailure

And that is deployed to https://function-start-failure.azurewebsites.net

Also, here are the logs I've found for host startup:

@andrew-rheingans Just curious to know why you need to use net8.0-windows as the TargetFramework value for your dotnet-isolated function app. What are you missing when you use net8.0 as the TargetFramework value ?

I use the function to generate some images and the package that generates those images targets net8.0-windows.
