azure-functions-host: [Bug] Host Error during the Function Run / Startup with the Version 7 of two NuGet Packages in Azure Functions .NET 6 V4

Is your question related to a specific version? If so, please specify:

Azure Functions V4 - .NET 6 Basic HTTP Trigger Packages:

  1. Microsoft.EntityFrameworkCore - 7.0.1 Stable Version
  2. Microsoft.Extensions.Configuration.Abstractions - 7.0.0 Stable Version

When I run the basic Http Trigger Function with above versioned packages, it is giving me different errors such as:

Net6v4NuGetPackages7vsn

With Version 6 of both NuGet Packages:

Net6v4NuGetPackages6vsn

What language does your question apply to? (e.g. C#, JavaScript, Java, All)

.NET 6 Core Visual Studio 2022 (17.4.3) Azure Functions Core Tools 4.0.4785

Question

I have seen that Entity Framework core Version 7.0.1 is released 2 days ago and M.E.Config.Abstractions Version 7.0.0 is released a month ago and has the compatibility with .NET 6 to 7.

Version 7 Packages are causing the Host Exceptions in Azure Functions .NET 6. Few issues reported in Stack Overflow Forum such as:

  1. 74470489
  2. 74808187

Please help to fix the issue.

@biste5 Thanks! I was able to make it run yesterday. I made all Microsoft.* packages to be at 6.0.0 and it worked with .NET 6… My best regards!

@daspurubairesdev switch to isolated-mode and .NET 7

Having the same issue here, .NET v6, Azure Functions V4, and I need to update my EF projects because Azure decided to upgrade my MySQL server to the latest version and so I need to update the MySQL driver which only works with the latest EF version, we are on a loop and we need to solve this. Any news? Thanks!!

@nicholasamiller : if you’re running in-process, that’s not supposed to work because in-process model is not expected to support .NET 7. If you’re running in isolated mode, then it should work with .NET 7
