Why do the UserClaims and RoleClaims tables not accept the Id with the Guid type?

[evolution-services]

I already tried according to the documentation:

https://learn.microsoft.com/en-us/aspnet/core/security/authentication/customize-identity-model?view=aspnetcore-7.0

But without success.

I believe this code snippet explains a lot about this:

using System;
using System.Security.Claims;
namespace Microsoft.AspNetCore.Identity;

///

/// Represents a claim that a user possesses.
///

/// The type used for the primary key for this user that possesses this claim.
public class IdentityUserClaim where TKey : IEquatable
{
///

/// Gets or sets the identifier for this user claim.
///

public virtual int Id { get; set; } = default!;
...
}

Where the public virtual int Id { get; set; } = default!; does not allow us to change the type of the property, as it is typed as int.

I believe they could have implemented it as IdentityUser which uses Guid as a key, I don't understand why it should be set to int where we might have more information about the user.

Although int supports a little more than 2 billion records, over time removing and recreating data for example, critical action may be necessary.

Guid would already solve this problem.

I've already made a few attempts and I didn't succeed.

When creating the migration, the result is always the same for the Id column:

migrationBuilder.CreateTable(
name: "AspNetUserClaims",
columns: table => new
{
Id = table.Column(type: "int", nullable: false)
.Annotation("SqlServer:Identity", "1, 1"),
UserId = table.Column(type: "uniqueidentifier", nullable: false),
ClaimType = table.Column(type: "nvarchar(max)", nullable: true),
ClaimValue = table.Column(type: "nvarchar(max)", nullable: true)
},
constraints: table =>
{
table.PrimaryKey("PK_AspNetUserClaims", x => x.Id);
table.ForeignKey(
name: "FK_AspNetUserClaims_AspNetUsers_UserId",
column: x => x.UserId,
mainTable: "AspNetUsers",
mainColumn: "Id",
onDelete: ReferentialAction.Cascade);
});

If anyone knows how to solve it I would be grateful.
