When EF7 RC is referenced from a Function App, the app throws a runtime error on startup

A minimal reproduceable repo is here: https://github.com/elninoisback/ef7rc-fnapp-issue

The following error is thrown in the console when the function app startsup. It goes away when you remove the ef core dependancy,

The 'Function1' function is in error: Could not load file or assembly 'Microsoft.Extensions.Logging.Abstractions, Version=7.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

The following is my .csproj file of the function app.

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <RootNamespace>ef7rc_fnapp_issue</RootNamespace>

EF Core version: 7.0.0-rc.1.22426.7 Database provider: (e.g. Microsoft.EntityFrameworkCore.SqlServer) Target framework: (e.g. .NET 6.0) Operating system: Windows 10 Pro IDE: Visual Studio Enterprise 2022

hmm looks to me that the aspnetcore shared framework is referenced right? if so ensure that:

    <!-- We need to enable this. -->
    <GenerateDependencyFile>true</GenerateDependencyFile>

in the csproj of the function application.

Currently I would recommend for you to test this with .NET 7’s TFM and see if you can still reproduce it with that as well.
