The API reference is generated from published NuGet packages. It covers types, methods, and extension points for each package and version.

## Browse

Start at the default v5 AutoFixture package:

[**AutoFixture 5.0.0-rc.1 API**](/api/autofixture/5-0-0-rc-1)

Or open [/api](/api) to land on the latest primary package.

## Package picker

Use the package and version selectors in the API layout to switch between:

- Core **AutoFixture** and extension packages (AutoFixture.Xunit3, AutoMoq, Idioms, …)
- **v5** and **v4** versions of the same package id
