-Provides a chance to validate the properties of the DTO object itself, as opposed to doing validation in `BeforeSave` of the properties of the model after the DTO has been mapped to the model.

+Provides a chance to validate the properties of the DTO object itself, as opposed to doing validation in `BeforeSave` of the properties of the model after the DTO has been mapped to the model. This also where [attribute-based validation](/topics/security.md#attribute-validation) is performed. 
 
 To perform custom validation in this method (uncommon), there are a number of extension methods on `IClassDto<T>` that can be used to access the value of the properties of [Generated C# DTOs](/stacks/agnostic/dtos.md). For behaviors on [Custom DTOs](/modeling/model-types/dtos.md) where the DTO type is known, simply cast to the correct type.
