Workleap.ComponentModel.DataAnnotations

Provides multiple new data annotation attributes, such as [Guid], [NotEmpty], [ValidateProperties].

Getting started

dotnet add package Workleap.ComponentModel.DataAnnotations

Decorate your properties, fields and method parameters with these new data annotation attributes.

Most of them are validation attributes that can be used in model validation. They work the same way as built-in .NET data annotations such as [Required], [Range], [RegularExpression], etc.

The most useful validation attribute here is probably ValidatePropertiesAttribute, as it validates all the properties of an object. This allows in-depth, nested validation of an entire complex object graph.
