xUnit converting IDictionary to IEnumerable

I've been searching the web for a way to make an IEnumerable in the Setup of a Mock by converting the Values of my IDictionary to it (either directly or conversion from '=List to IEnumerable). However I have only come across the latter.

Inspiration Sources:

  1. IEnumerable<object> a = new IEnumerable<object>(); Can i do this?
  2. Convert dictionary with List to IEnumerable
  3. Convert dictionary of any type to IEnumerable collection

  4. How to use Moq to return a List of data or values?

    public class UserServiceTests
{
    private Mock<IUserRepository> _userRep { get; set; }

    // fake app repository to get data from
    private IDictionary<int, User> _userRepData { get; set; }

    private UserService _sut { get; set; }

    public UserServiceTests()
{
    _userRepData = new Dictionary<int, User>();

    _userRep = new Mock<IUserRepository>();

    // Been able to create the proper list using:
    // List<User> usersList = _userRepData.Values.ToList<User>(); 
    // IEnumerable<User> users = appsList.AsEnumerable();
    // So I am looking for away to replicate this in my setup method
    // Obviously know the below is not the correct syntax.
    _userRep.Setup(r => r.GetUsers()).Returns(() => new IEnumerable<User> {_userRepData.Values.ToList<User>} );

    _sut = new UserService(_userRep.Object);
}

[Fact]
public void GetUsers_succeeds_at_getting_all_users_from_repository()
{
    User user1 = new User();
    User user2 = new User();

    _userRepData.Add(1, user1);
    _userRepData.Add(2, user2);

    IEnumerable<User> users = new User[] { user1, user2 };

    _sut.GetUsers().Should().BeSameAs(users); // Note: fluentassertions
}

    }

Values already implements IEnumerable<T>.
You can return it directly; you don't need to create anything.
