Intent.ValueObjects

This module provides a simple Value Object implementation in C# based on the Microsoft suggested pattern.

What is a ValueObject

More information can be found on the official Microsoft documentation website, but in summary:

• Value Objects do not have an identity – they are defined solely by their attributes.
• They are immutable – once created, their state cannot be changed.

What's in this module?

• Microsoft suggested pattern implementation.
• Domain Designer extensions that enable modeling ValueObjects in the Domain Designer.

Modelling ValueObjects

Once this module is installed, the New Value Object menu item will be available, allowing Value Objects to be added in the Domain Designer.

ValueObjects are modelled in a similar fashion to Entities.

ValueObjects and Primary Keys

Note

Value Objects should not be modeled with a primary key.

Unlike Entities, which have a unique identifier, Value Objects are defined by their attributes rather than an identity. If two Value Objects have the same data, they are considered equal. Therefore, assigning a primary key would contradict their purpose and introduce unnecessary complexity. Instead, Value Objects are typically embedded within Entities rather than stored as separate database records.
