.NET 8 Azure Function App Error: Could Not Load File or Assembly 'Microsoft.Extensions.Logging.Abstractions'

I recently upgraded an Azure Function App from .NET 6 to .NET 8 and encountered an issue during local execution. The project compiles successfully, but when running it locally, I face the following assembly loading error:

function is in error: Could not load file or assembly
‘Microsoft.Extensions.Logging.Abstractions, Version=8.0.0.0

This problem seems to relate to Microsoft.Extensions.Logging.Abstractions and appears to be a common issue with .NET 8 based on my research and similar issues reported on Stack Overflow:

Azure Function in .Net 6 giving error Could not load file or assembly

and

Could not load file or assembly Microsoft.Extensions.Logging.Abstractions

Downgrading to .NET 6 is not an option for me, as other projects in the solution that the Function App depends on have been upgraded to .NET 8, and reverting those changes would lead to compatibility issues.

I came across the concept of "Isolated Mode" in Azure Functions, which seems like it might be a solution to my problem, but I’m unsure how to implement it in my current setup or if it’s even the right approach.

Here’s the project file (*.csproj) for my Function App:

This is the project file of the fuction app:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <DockerFastModeProjectMountDirectory>/home/site/wwwroot</DockerFastModeProjectMountDirectory>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
  </PropertyGroup>

  </ItemGroup>
  <ItemGroup>

    //These Projects are now .net 8.0
    <ProjectReference Include="..AsoRockFood.com.Umbraco.ModelsAsoRockFood.com.Umbraco.Models.csproj" />
    <ProjectReference Include="..RockLife.ServicesAsoRockFood.com.Services.csproj" />

  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

How can I resolve the assembly loading error without downgrading my .NET version?

Is switching to Isolated Mode a viable solution? If so, how should I go about implementing it in my Function App?

Any insights or suggestions would be greatly appreciated.

Thank you in advance!
