nValid

Fluent validation library for .NET

With nValid, you can cleanly define validation rules for any .NET type, and validate instances of types with a very simple syntax.

Features

The main features are:

• Fluent interface for configuration
• Can validate any POCO
• Zero dependencies
• Easily extensible
• Can use resources to set error message (localization support).
• Basic support for named validation contexts.

Planned features

The following features are not yet available, but are planned:

• Client-side validation. We want to be able to generate client-side validation logic based on our rulesets. Either integrate with an existing library (for example, xVal), or develop our own solution.
• Cleaner way to setup rules. The current syntax for registering rules makes it hard to organize a large number of rulesets. We need a clean way to have rulesets in individual files. Probably something similar to StructureMap's registries.

Project status

The project is still in an early stage. I would love to receive comments, code reviews, suggestions and/or patches. You can reach me at comments@nvalid.net.

Right now I work on nValid when I need it to do something it doesn't currently do.

Thanks
