I recently spoke about Event Sourcing at the inaugural LevelsConf 2018. You can find the abstract and slides here.
NimbleConfig is an open source configuration injection library for .NET with full support for ASP.NET CORE. It allows you to use configuration settings in as very simple and testable way.
NEventLite is an open source Event Sourcing library for .NET that can get your ES+CQRS project up and running quickly and hassle free. It helps you manage the aggregate lifecycle and supports many event storage providers.
