Microsoft.Extensions.DependencyInjection.Abstractions: Unable to resolve service for type

[exhesham]

I am receiving the next error when running the Basic Demo:

[5/23/2019 12:38:21 PM] Executed 'SampleFunction' (Failed, Id=d27a090a-4ddf-4e5c-92e6-660646c81be9)

What am I missing?

@fabiocav is this same issue as e.g Azure/azure-functions-host#4939, Azure/azure-functions-host#4914 and or Azure/azure-functions-host#3399? A bit hard to follow and what's really related (type of DI and or service lifetime) as well as what is/will be fixed (by 1.0.30)?

AddHttpClient and AddDbContext (EF) seems to work just fine

I moved to AWS Lambda due to too much problems with Azure.
