you can use this code in your controller:
ViewBag.Categories = new SelectList(List of categories for show in view, "Id", "Name");
if you have categories in your data base you can make a query for get list of categories or you can make a list of categories with Id and Name then pass the list into first parameter of SelectList.
in your View:
<div class="form-group">
<label>Categories :</label>
<select name="CategoryId" asp-for="CategoryId" class="formcontrol" asp-items="ViewBag.Categories">
<option value="">Please choose user category:</option>
</select>
<span asp-validation-for="CategoryId" class="text-danger"></span>
</div>
or generate it by tag helper:
@Html.DropDownListFor(model => Category ,ViewBag.Categories as SelectList, new { @class = "form-group"} )
