IRegistrar interface

Describes the IRegistrar interface in Optimizely Customized Commerce 13.

The IRegistrar interface supports self-registered users who do not need back-end access functionality. A common use case for this is a user store for management functions of your site, and another user store for customers who buy goods from your ecommerce site.

The interface uses EPiServer.ServiceLocation.ServiceLocator to register the default instance of the interface. Then, in your front-end code, use the ServiceLocator instance when writing your controllers, so you can easily switch to a new IRegistrar user store in the future if needed.



This configuration requires the EPiServer.Commerce.Security NuGet package as dependency.
