Serverless.

Running an ASP.NET app in AWS Lambda is just a few lines of code. However, all of a sudden startup time becomes important for both performance and cost.

These investments by Microsoft and others[1] allow .NET to remain relevant and viable for modern use cases.

Serverless is great, but if you want to go that route you should be aware that it is in no way a typical hosted ASP.NET app, and while you can "Run an ASP.NET app in AWS Lambda" with little code, there are are better ways to design a Lambda.

Can you elaborate on “is in no way a typical hosted ASP.NET app”?

I get that the machinery under the hood is different (ie. Kestrel web server may not get used). However, we typically don’t care about those details. Our ASP.NET code runs in 3 separate places (containers, servers, Lambda) and the only difference between all 3 is a single entry point file.

Do you mean because Lambda is only serving one request at a time and has a more ephemeral host process lifetime?

Yes, a typical hosted ASP.NET app is neither ephemeral or one request at a time. So this drives different design decisions.
