ASP.Net MVC Dropdown text generation using a Select List not populating the values and text

Using the following code i generate a select list in my controller and feed it into my view model.

var SelectListItems = om_repo.List().Select(x => {
            var item = new SelectListItem();
            item.Value = x.id.ToString();
            item.Text = x.code;
            return item;
        });

createvm.allOccupations = new SelectList(SelectListItems);

Here is my view code

@Html.DropDownListFor(model => model.selectedOccupation,  Model.allOccupations, "Choose one")

The output im getting is 

<option>System.Web.Mvc.SelectListItem</option>

Why isnt it picking up the select list items Text and Values that are being fed. In my debugger i can see the values are set in the locals under text and value.

Because the DropDownlist doesn't want a SelectList; it wants an IEnumerable of SelectListItems.

Try just:

createvm.allOccupations = SelectListItems;

Model Class also needs to be:

public IEnumerable<SelectListItem> allOccupations { get; set; }

Not

public SelectList allOccupations { get; set; }
