ASP.NET Identity change password

Question

I need ability to change password for user by admin. So, admin should not enter a current password of user, he should have ability to set a new password. I look at ChangePas

This is just a refinement on the answer provided by @Tseng. (I had to tweak it to get it to work).

public class AppUserManager : UserManager
{
    .
    // standard methods...
    .

    public async Task ChangePasswordAsync(AppUser user, string newPassword)
    {
        if (user == null)
            throw new ArgumentNullException(nameof(user));

        var store = this.Store as IUserPasswordStore;
        if (store == null)
        {
            var errors = new string[] { "Current UserStore doesn't implement IUserPasswordStore" };
            return IdentityResult.Failed(errors);
        }

        var newPasswordHash = this.PasswordHasher.HashPassword(newPassword);
        await store.SetPasswordHashAsync(user, newPasswordHash);
        await store.UpdateAsync(user);
        return IdentityResult.Success;
    }
}

Note: this applies specifically to a modified setup that uses int as the primary keys for users and roles. I believe it would simply be a matter of removing the type args to get it to work with the default ASP.NET Identity setup.
