ASP.NET Core applications can be run serverless in AWS Lambda as-is and still be run locally or in a container.

Introduction​

Since AWS Lambda functions are lightweight containerized Amazon Linux runtimes that can run .NET Core 3.1, you can run a mostly regular ASP.NET Core workload on them just the same.

When I first started using .NET Core, all the examples online for applications were for web applications using ASP.NET Core. However, I wanted to start simpler and build a simple command line tool. This required a LOT of trial and error in manually setting up configuration, logging, dependency injection, and tearing everything down appropriately so that all the logging output would properly get flushed. I kept that example around ... somewhere ... and had to refer my coworkers to it a few times over the year. Now with .NET Core 3.1 and the new Generic Host, we can get a simple (but fully featured) command line application built up following Vertical Slice Architecture.
