As a part of package updation, we have updated 'Microsoft.Extensions.Logging.Abstractions, to the latest version 8 and after this azure function is not working and we are seeing below error message in azure function User's image

While build locally also we are getting the below error, Microsoft.Azure.WebJobs.Script: Error configuring services in an external startup class. AzureFunction: Could not load file or assembly 'System.ComponentModel, Version=7.0.0.0, Culture=neutral, PublicKeyToken=fghfg'. The system cannot find the file specified.

lakshmi Thanks for posting your question in Microsoft Q&A. Can you share .csproj, .json settings, Core Tools version?

We are using .net version 7 Below are the .cs project details for azure function

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
	<ErrorOnDuplicatePublishOutputFiles>false</ErrorOnDuplicatePublishOutputFiles>
    <TargetFramework>net7.0</TargetFramework>

      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

In the reference project Domain , we have installed the latest package of Microsoft.Extensions.Logging.Abstractions. In the Doamin project we are using semantic kernel for using open ai feature and semantic kernel needs the latest version of Microsoft.Extensions.Logging.Abstractions

It looks like you are using in-process model which only supports .NET 6.0 (LTS). If you are looking to use .NET 7.0 or .NET 8.0, I suggest you use isolated model as described in https://learn.microsoft.com/en-us/azure/azure-functions/functions-dotnet-class-library?tabs=v4%2Ccmd#supported-versions.

To answer the question on the exception, the dependencies are restricted to 6.0.0 as discussed in this thread and you might face similar errors with unsupported version like .NET 7.0 (similar discussions: https://github.com/Azure/azure-functions-host/issues/9685#issuecomment-1812042873, https://github.com/Azure/Azure-Functions/issues/2319). Hence you can either downgrade and validate with .NET 6.0 for in-process model or move to Isolated model for latest .NET versions.

I hope this helps and let me know if any questions.

Hi,
I am also facing the similar issue. Recently I have migrated the Azure function apps from .net 6 to .net 8 with inprocess model itself . So within my .csproj file I have updated the target framework to .net 8 and updated the "Microsoft.NET.Sdk.Functions" Version="4.1.1" to "4.4.1. It didnt give any runtime time errors in my local. I was even able to execute the functions. But when deployed to azure portal it was giving the below error. Can someone please help.
