.NET Core using Azure B2C Authentication, looking for the User Attributes such as @User.Identity.UserID after logged in

问题

I'm using .NET Core, with Azure B2C Authentication. On the project I'm developing, I can find the @User.Identity.Name, but I cant find the C# object name/path for the other "built in" User Attributes such as @User.Identity.UserID , @User.Identity.firstTimeLogging, @User.Identity.firstName. These Attribute are enabled in Azure AD. Thank you for your time.

You can access custom claims by including them in the token sent to the app or by querying the Azure AD Graph API (not the Microsoft Graph yet).

For the first option reading it from claim , you can follow below thread :

For the other option , using graph api to get user details , you can browse the below doc for the same:

Hope it helps.

Thanks to Mohit, this is the solution I found.

var claimsIdentity = (System.Security.Claims.ClaimsIdentity)User.Identity;

 List<String> termsList = new List<String>();
    foreach (var claim in claimsIdentity.Claims)
    {
        termsList.Add(claim.Value);
    }
   //The 2nd item in the claim is the objectidentifier
    Debug.WriteLine(termsList[2]); 
// there is probably a cleaner way, but it works for me.
