I cannot figure out how to upload a function.proj file.
https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-csharp#referencing-external-assemblies led me to https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference#fileupdate
but neither of them have any screenshot showing where the button is. I searched some other SO post such as this How can I use NuGet packages in my Azure Functions?
But my UI is different than the OP maybe the UI has been updated?
This is the error I am getting,
