I'm currently working on two different projects: Kledex and Weapsy.
Kledex (formerly OpenCQRS) is a .NET Core framework that can be used to create a simple and clean design by enforcing single responsibility and separation of concerns. Its advanced features are ideal for Domain Driven Design (DDD), Command Query Responsibilty Segragation (CQRS) and Event Sourcing. Kledex also has Azure Service Bus and RabbitMQ integrations.
Weapsy is going to be an ASP.NET Core Blog/CMS which will use Kledex as base framework. Weapsy will be multi language and extensible, in fact developers will be able to create their own plugins in order to create content.
