Validation Aspects 2.1.0

Here are some key features of "Validation Aspects":

· Object Validation - Objects can be queried to determine if their state is valid against a set of validation rules. Validation messages and context of what/where validation failed is reported via a ValidationResult.

Property Validation - Multi-Mode validation. The following modes can be enabled or disabled independantly to suit your chosen method of validation:
· - Interception Validation - Validation is invoked when the property is set. If the validation fails, a validation exception will throw to ensure the model does not become invalid.
· - State Validation - Validation is invoked when the object is validated. If the validation fails, the validation failure is added to the ValidationResult.

· Parameter Validation - Parameter validation checks the validity of the value as determined by code contracts and business rules. If the validation fails, a validation exception will throw to ensure the model does not become invalid.
· Real-time augmentation / replacement - Validation can be changed programmatically or via configuration.

· AOP - Validation Aspects are applied to your models by PostSharp. There are no base classes to derive from or interfaces to explicitly implement.

· Custom Validators - Implement new validators easily with minimal code with lambda syntax.

· Strongly-typed validation targets - Compile-time checking ensures validation is correctly declared - you can't declare a numeric validator to validate a string. Validators are implemented to target certain types. Incorrectly declared validators applied at run-time fail fast.

· Integration - Support and samples for WPF. Asp.net MVC server/client-side and Silverlight coming soon.

· Localization - Validation exception messages can be customized with message formatting functions.

· TDD'd - Near 100% code coverage from hundreds of unit tests.

Requirements:

· NET Framework 3.5
· PostSharp v1.0 RTM
