NSpecification 1.3.0

NSpecification is the most complete library for the Specification pattern and it's grounded on the Domain-Driven Design principles. Provides interface, abstract and a generic specification, composable, supports operators. This is probably the most fluent and least verbose library. Specifications can be composed with real operators (&, |, !, ==, !=). They are interchangeable with Expression<Func<T, bool>> and Func<T, bool> and can be combined directly with boolean expressions. Check the tutorial in the GitHub.

NSpecifications - Specifications on .net

What is the Specification Pattern?

When selecting a subset of objects, it allows to separate the statement of what kind of objects can be selected from the object that does the selection.

Ex:

A cargo has a separate storage specification to describe what kind of
container can contain it. The specification object has a clear and
limited responsibility, which can be separated and decoupled from the
domain object that uses it.

What can you do with Specification Pattern?

  1. Validate an object or check that only suitable objects are used for a certain role
  2. Select a subset of objects based a specified criteria, and refresh the selection at various times
  3. Describe what an object might do, without explaining the details of how the object does it, but in such a way that a candidate might be built to fulfill the requirement
