An expression tree may not contain a dynamic operator

I'm trying to join two tables. User and Scoreboard

ViewModels>ScoreboardVM.cs

public class ScoreboardVM
{
public IEnumerable<dynamic> Scoreboards { get; set; }
}

Controller

var db = new GameDBDataContext();
var userList = (from s in db.Scoreboards
               join u in db.Users on s.User equals u.UserId
               select new { UserName = u.UserName }).Take(5);

var viewModel = new ScoreboardVM();
viewModel.Scoreboards = userList;

return View(viewModel);

View

@model Project.ViewModels.ScoreboardVM
    @foreach (var item in Model.Scoreboards) {
    @Html.DisplayFor(model => item.UserName) }

The last line returns the error "An expression tree may not contain a dynamic operator" and I'm not sure what that means.

The error you aree getting is because the public IEnumerable<dynamic> Scoreboards is dynamic and @foreach (var item in Model.Scoreboards) which is dynamic is not supported by the lambda expression
