I made a prototype using .NET Core MVC + Entity Framework + Npgsql + Autofac (Probably better IoC containers available out there but I'm used to Autofac open to suggestions btw).

It was very easy to develop, test and deploy. Npgsql has support for most of the postgres features (except complex types but that's planned).

I deployed everything on Ubuntu servers and runs like a champ. (I'm saying prototype and it is indeed, but it has 100-something users across the globe testing their workflows continuously and it has a lot of CPU-intensive stuff which is child's play with .NET to manage asynchronously. A production app would have two orders of magnitude more users but I think I'll be able to get away with a single server if it comes to that).

What was your experience upgrading a dotnet-core app?

We had a couple experiments at my company but going from 1.0 to 1.1 had breaking changes so we couldn’t upgrade easily.

I think everything was beta-quality until 2.0 - so yeah it wasn't easy. Nowadays it's smooth sailing.
