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 e-commerce 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.
