The Ncqrs Framework

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.

Build locally

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.

Discussion and feedback

The best source for discussion is the ncqrs-dev group. You could also drop quick messages to us using twitter.

To submit a bug or make a feature request use github issues.


Since the code base of Ncqrs will never be complete. We encourage users to fork Ncqrs code, make changes, commit them to your forked repository, and submit pull requests.

You can use our [Redmine environment] to find support our project management. Use it to submit a bug, request a feature and to see our roadmap.

Why does git show that all of my files are modified?

Ncqrs is built by Windows users, so all of the text files have CRLF line endings. These line endings are stored as-is in git (which means we all have autocrlf turned off). If you have autocrlf enabled, when you retrieve files from git, it will modify all of your files. Your best bet is to turn off autocrlf, and re-create your clone of Ncqrs.

  1. Delete your local clone of the Ncqrs repository
  2. Type: git config --global core.autocrlf false
  3. Type: git config --system core.autocrlf false
  4. Clone the Ncqrs repository again
