I've used Azure's serverless offering "Functions" quite a bit. The dev experience is pretty good, actually - it "just works" - start it and point your browser at the URL. And certainly no problems setting up env vars or anything basic like that.
My only nitpick, and only specifically relating to dotnet, is that config files and env vars differ between Functions and regular ASP.NET Core web apps. I think there is some work going on to fix that, but it's taking forever.
