FunctionsStartup not being called after installing Microsoft.AspNetCore.Authentication.Facebook, causing DI failure

Question

I am using the latest Microsoft.NET.Sdk.Functions 3.0.7. After installing Microsoft.AspNetCore.Authentication.Facebook FunctionsStartup doesn't execute causing DI failure. Not sure if this is related to the sdk update or the fb nuget, but if I uninstall the fb nuget FunctionsStartup works fine again.
