This package is an optional (but recommended) add-on to CSF.Validation. The standard rules package provides a number of pre-written rules for common validation scenarios.
Reference this package from both your application startup and your project(s) which perform validation.
In application startup, whilst configuring dependency injection, use the UseStandardValidationRules method to register them with DI.
In your validators you may now use these rules like any others.
This package also provides capabilities for validating a validator - a sanity-check to verify that the composition of a validator does not contain obvious errors.
See the type IValidatesValidationManifest for this capability.
For more information, please see the documentation website.
