Incorrect Method for SelectList selected item

[paulcdavey]

Description

The following code does not do what is described:
DepartmentNameSL = new SelectList(departmentsQuery.AsNoTracking(), nameof(Department.DepartmentID), nameof(Department.Name), selectedDepartment);
The 4th argument "selectedDepartment" does not do anything in this context because in the select tag helper, the asp-for parameter is specified as "Course.DepartmentID".
<label asp-for="Course.Department" class="control-label"></label> <select asp-for="Course.DepartmentID" class="form-control" asp-items="@Model.DepartmentNameSL"> <option value="">-- Select Department --</option> </select> <span asp-validation-for="Course.DepartmentID" class="text-danger"
The selected option is driven by Model.Course.DepartmentID.

The same mistake is perpetuated throughout the tutorial.
