Ncqrs is a framework for .NET helps build scalable, extensible and maintainable applications by supporting developers apply the Command Query Responsibility Segregation (CQRS) architectural pattern. It does so by providing an infrastructure and implementations for the most important building blocks for command handling, domain modeling, event sourcing, and so. These building blocks help you to focus on the code that adds business value. They come with annotation, convention and configuration support and help you to write isolated and testable. Run BUILD.bat to build the Ncqrs Framework. This will build the framework, run all the tests and updates all the lib folders of other solutions (extensions and sample) with the result.
