Add claims when creating a new user

Question

I am creating a new User using ASP.NET Core Identity as follows:

new User {
  Email = "john@company.com",
  Name = "John"
}

await userManager.CreateAsync(user, "password");

I need to add a Claims when creating the user. I tried:

new User {
  Email = "john@company.com",
  Name = "John",
  Claims = new List<Claim> { /* Claims to be added */ }  
}

But Claims property is read only.

What is the best way to do this?

I am not looking to save data in the authentication cookie. I am looking to saving adding claims to the user and save it to the database — Miguel Moura, Sep 19 '16 at 16:58
I didn't test it but as far as i understand from comments claims are saved in database. — adem caglin, Sep 19 '16 at 17:01
await UserManager.AddClaimAsync(user, new Claim("your-claim", "your-value")); — agua from mars, Sep 19 '16 at 17:02

You can use UserManager<YourUser>.AddClaimAsync method to add a claims to your user

var user = new User {
  Email = "john@company.com",
  Name = "John"
}

await userManager.CreateAsync(user, "password");

await userManager.AddClaimAsync(user, new System.Security.Claims.Claim("your-claim", "your-value"));

Or add claims to the user Claims collection

var user = new User {
  Email = "john@company.com",
  Name = "John"
}

user.Claims.Add(new IdentityUserClaim<string> 
{ 
    ClaimType="your-type", 
    ClaimValue="your-value" 
});

await userManager.CreateAsync(user);
