NLog is a free logging platform for .NET with rich log routing and management capabilities. It makes it easy to produce and manage high-quality logs for your application regardless of its size or complexity.
It can process diagnostic messages emitted from any .NET language, augment them with contextual information, format them according to your preference and send them to one or more targets such as file or database.

Contributing
As the current NLog team is a small team, we cannot fix every bug or implement every feature on our own. So contributions are really appreciated!
If you like to start with a small task, then up-for-grabs are nice to start with.
Please note, we have a dev and master branch
masteris for pure bug fixes and targets NLog 4.xdevtargets NLog 5
A good way to get started (flow)
- Fork the NLog repos.
- Create a new branch in you current repos from the 'dev' branch. (critical bugfixes from 'master')
- 'Check out' the code with Git or GitHub Desktop
- Check [contributing.md](.github/CONTRIBUTING.md#sync-projects)
- Push commits and create a Pull Request (PR) to NLog
Please note: bugfixes should target the master branch, others the dev branch (NLog 5)
