Upgrade to NET6 - Functions failed to start

Hello,

I have just recently tried to upgrade our installation of Company Communicator from version 5.2.0 to the latest 5.3.0.

The upgrade instructions were followed exactly as provided but the Function Apps (all 3) where failing to start, throwing the error: AZFD0005:

Message
Error building configuration in an external startup class.
Details
Microsoft.Azure.WebJobs.Script.ExternalStartupException : Error building configuration in an external startup class. ---> Microsoft.Azure.WebJobs.Script.HostInitializationException : One or more loaded extensions do not meet the minimum requirements. For more information see https://aka.ms/func-min-extension-versions. ExtensionStartupType DurableTaskWebJobsStartup from assembly 'Microsoft.Azure.WebJobs.Extensions.DurableTask, Version=2.0.0.0, Culture=neutral, PublicKeyToken=014045d636e89289' does not meet the required minimum version of 2.4.1. Update your NuGet package reference for Microsoft.Azure.WebJobs.Extensions.DurableTask to 2.4.1 or later. ExtensionStartupType ServiceBusWebJobsStartup from assembly 'Microsoft.Azure.WebJobs.ServiceBus, Version=3.0.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not meet the required minimum version of 4.2.1.0. Update your NuGet package reference for Microsoft.Azure.WebJobs.Extensions.ServiceBus to 4.2.1 or later (...)

The error is basically saying I’d need to update NuGet references to use the latest versions for some libraries. It does not make much sense to me as the libraries being referenced by CC are already versions greater than the minimum required.

Anyone else had this issue? And how to solve it?

Thank you in advance.

Hello @gsv022,

As stated in my previous comment, the problem was indeed with the AzureWebJobsDashboard setting (it is not compativle with ~4 runtime).

I have then removed the AzureWebJobsDashboard App Setting entry from my environment (all functions & app service), re-deployed everything and it is now working as expected.

Thank you for your time looking into this.

I will close this ticket.

Cheers. Victor.

@victorsimonlee , Please note that the latest features such DOTNET upgrade .NET 6 , Azure Functions(~4), App service compatible to .NET 6 are part of latest version i.e., 5.3. This latest version code will be always be present in main branch of official repository. If the branch is pointing to main then functions will fail for sure.

Please let us know if you have any queries.
