You are developing an application that uses ASP.NET Core Identity for authorization. The application must use an existing Microsoft Azure Table Storage instance to store user information. You create a custom UserStore class.
You need to register the class as a dependency.
Which two interfaces should you implement? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. IUserSecurityStampStore
B. IUserLoginStore
C. IQueryableUserStore
D. IUserStore
E. IUserPasswordStore
Correct Answer: BD
Explanation/Reference:
D: Create a UserStore class that provides the methods for all data operations on the user. This class is equivalent to the UserStore class. In your UserStore class, implement IUserStore<TUser> and the optional interfaces required. You select which optional interfaces to implement based on the functionality provided in your app.
Interfaces to implement when customizing user store
IuserStore
The IUserStore<TUser> interface is the only interface you must implement in the user store. It defines methods for creating, updating, deleting, and retrieving users.
IuserLoginStore
The IUserLoginStore<TUser, TKey> defines the methods you must implement in your user store to enable external authentication providers. It contains methods for adding, removing and retrieving user logins, and a method for retrieving a user based on the login information.
