Change Keys for Users

Question

I'm currently working with a website which is being developed in ASP.NET and C#. I'm using EF6 and need to change the default tables to my own custom tables. I have managed to do that with a problem. In my custom table the UserId is an int rather than default nvarchar(128) . I am following this demo but I keep getting an error at the first line.

public class ApplicationUser : IdentityUser<int, CustomLogin>
{
}

The error is: " The non-generic type Microsoft.AspNet.Identity.EntityFramework.IdentityUser " cannot be used with type arguments.

I did some research and came across this post . I have updated all the core libraries but the error still exists. Has anyone else faced this problem before or am I the lucky one? Thanks in advance for your help

Answer 1

There are two IdentityUser classes that come with ASP.NET. One is declared as:

public class IdentityUser : IdentityUser<string, 
        IdentityUserLogin, 
        IdentityUserRole, 
        IdentityUserClaim>, IUser

and the other is:

public class IdentityUser<TKey, TLogin, TRole, TClaim> : IUser<TKey>
        where TLogin : IdentityUserLogin<TKey>
        where TRole : IdentityUserRole<TKey>
        where TClaim : IdentityUserClaim<TKey>

You will be declaring a subtype of the generically-typed class and will need all four generic types in the declaration. And you'll also need classes that inherit IdentityUserRole<int> , IdentityUserClaim<int> , along with your CustomLogin class, which I assume is a derivative of IdentityUserLogin<int> .

Folling your naming convention, you should declare your class as

public class ApplicationUser : IdentityUser<int, CustomLogin, CustomRole, CustomClaim>
