Conqueror | For building scalable & maintainable .NET applications

Conqueror is a C# library. Conqueror has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

CQS is an acronym for command-query separation (which is the inspiration for this project and also where the name is derived from: conquer -> commands and queries). The core idea behind this pattern is that operations which only read data (i.e. queries) and operations which mutate data or cause side-effects (i.e. commands) have very different characteristics (for a start, in most applications queries are executed much more frequently than commands). In addition, business operations often map very well to commands and queries, allowing you to model your application in a way that allows technical and business stakeholders alike to understand the capabilities of the system. There are many other benefits we gain from following this separation in our application logic. For example, commands and queries represent a natural boundary for encapsulation, provide clear contracts for modularization, and allow solving cross-cutting concerns according to the nature of the operation (e.g. caching makes sense for queries, but not so much for commands). With commands and queries, testing often becomes more simple as well, since they provide a clear list of the capabilities that should be tested (allowing more focus to be placed on use-case-driven testing instead of traditional unit testing).
