Question: How to add Autofac to LambdaEntryPoint in net core 3.0?

Hi,

I am testing out an api project with Amazon.Lambda.AspNetCoreServer and i stumbled upon a problem which i am not sure how to proceed with. Autofac has changed how its added: New way: With IHostBuilder .UseServiceProviderFactory(new AutofacServiceProviderFactory() Old Way: With IWebHostBuilder serviceCollection.AddAutofac() Also from my understanding IWebHostBuilder will be deprecated which LambdaEntryPoint is using in the Init method.

For the IWebHostBuilder when i try to add Autofac i get this info message from the method:

ONLY FOR PRE-ASP.NET 3.0 HOSTING. THIS WON’T WORK FOR ASP.NET CORE 3.0+ OR GENERIC HOSTING.

And i cant use IHostBuilder with LambdaEntryPoint.

Anyone has done this or has any ideas how to proceed? Thanks in advance!

Yeah I see now the continual use if IWebHostBuilder is a blocker for using Autofac in .NET Core 3.1. Sorry I should have switched to IHostBuilder as part of the major version change that went out with .NET Core 3.1. I was trying to avoid complexity with this library also supporting .NET Core 2.1 which does use IWebHostBuilder.

I don’t want to make significant set breaking changes just a couple weeks after the last major version came out so let me think if there is a less invasive approach to unblock you all.

Version 5.1.0 of Amazon.Lambda.AspNetCoreServer went out today with this change.

I also published a blog post that has a section describing the change. https://aws.amazon.com/blogs/developer/one-month-update-to-net-core-3-1-lambda/
