This repo contains the code used in my blog post about building modular monoliths in ASP.NET Core. If that sounds interesting, have a look at https://fearofoblivion.com/build-the-modular-monolith-first.
All the code should just work. To run the individual modules, just run dotnet run in the corresponding directory under the src directory. To run the "host", just start the FiftyNine.ModularMonolith.Api project, and it should come up.
Tests? Well, they are there, in VERY simple form! But they do show you how to test the individual modules, as well as the complete "host".
Questions? Well, I'm on twitter! Just ping me at @ZeroKoll!
