While working with MVC you dont see # tags which denotes aspx engine you will always see @ which denotes the razor engine.

So writing HTML in this engine is different as compared to aspx engine

@model MVC_Demo.Models.EmployeeModel

@{
    ViewBag.Title = "RegisterEmployeeDetails";
}

<h2>RegisterEmployeeDetails</h2>

<div>
    <h4>EmployeeModel</h4>
    <hr />
    <dl class="dl-horizontal">
        <dt>
            @Html.DisplayNameFor(model => model.FirstName)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.FirstName)
        </dd>

        <dt>
            @Html.DisplayNameFor(model => model.MiddleName)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.MiddleName)
        </dd>

        <dt>
            @Html.DisplayNameFor(model => model.LastName)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.LastName)
        </dd>

        <dt>
            @Html.DisplayNameFor(model => model.PhoneNo)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.PhoneNo)
        </dd>

        <dt>
            @Html.DisplayNameFor(model => model.Address)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.Address)
        </dd>

      
    </dl>
</div>
<p>
    @Html.ActionLink("Edit", "Edit", new { /* id = Model.PrimaryKey */ }) |
    @Html.ActionLink("Back to List", "Index")
</p>

Here you can see in HTML that  for labels we are writing Label DisplayFor
