Install-Package AspNetCore.Identity.Cassandra

Create your own User and Role entities

[Table("users", Keyspace = "identity")]
public class ApplicationUser : CassandraIdentityUser
{
    public ApplicationUser()
        : base(Guid.NewGuid())
    {
        
    }
}

[Table("roles", Keyspace = "identity")]
public class ApplicationRole : CassandraIdentityRole
{
    public ApplicationRole()
        : base(Guid.NewGuid())
    {
        
    }
}
