This topic describes using the IRegistrar interface in Episerver Commerce. This interface allows for the ability to have self-registered users who do not need any back-end access functionality. A common use case for this has a user store for management functions of your site, and another user store for customers who buy things from your e-commerce site. The idea behind the interface is to use EPiServer.ServiceLocation.ServiceLocator to register the default instance of the interface. Then in your front-end code you can use the ServiceLocator instance when writing your controllers so you could easily switch to a new IRegistrar user store in the future if need be. 

Note: This configuration requires the EPiServer.Commerce.Security nuget packages as dependency.  

Interface methods

  • IPrincipal CreateUser(string userName, string password, string email);. Creates a user in the user store and then returns a ClaimsPrincipal. The principal should contain the following claims for roles Everyone and Registered.
