How to get and set Claim for arbitrary users in Asp.Net Core Indetity?

Question

ASP.NET

I can not find a clear example of how you can get Claims for an arbitrary user and how you can set it. This is not about the current user.

For example, how do you list all users and all the claims they have installed? Second example, how to create, edit and delete claims for an arbitrary application user?

services.AddScoped<IUserClaimsPrincipalFactory<ApplicationUser>,
                AdditionalUserClaimsPrincipalFactory>();

public class AdditionalUserClaimsPrincipalFactory
        : UserClaimsPrincipalFactory<ApplicationUser, IdentityRole>
    {
        public AdditionalUserClaimsPrincipalFactory(
            UserManager<ApplicationUser> userManager,
            RoleManager<IdentityRole> roleManager,
            IOptions<IdentityOptions> optionsAccessor)
            : base(userManager, roleManager, optionsAccessor)
        { }

        public override async Task<ClaimsPrincipal> CreateAsync(ApplicationUser user)
        {
            var principal = await base.CreateAsync(user);
            var identity = (ClaimsIdentity)principal.Identity;

            var claims = new List<Claim>();
            claims.Add(user.IsAdmin ? new Claim(JwtClaimTypes.Role, "admin") : new Claim(JwtClaimTypes.Role, "user"));

            identity.AddClaims(claims);
            return principal;
        }
    }

public class ApplicationUser : IdentityUser
    {
        [PersonalData]
        public string Name { get; set; }
        [PersonalData]
        public DateTime BirthDate { get; set; }
        public bool IsAdmin { get; set; }
    }
