Brief the Pros and Cons of ASP.NET MVC WebForm or ASPX View Engine? | ASP.NET MVC Interview Question

A view engine that is used to render a Web Forms page to the response.
Pros:
  • ubiquitous since it ships with ASP.NET MVC
  • familiar experience for ASP.NET developers
  • IntelliSense
  • can choose any language with a CodeDom provider (e.g. C#, VB.NET, F#, Boo, Nemerle)
  • on-demand compilation or precompiled views
Cons:
  • usage is confused by existence of “classic ASP.NET” patterns which no longer apply in MVC (e.g. ViewState PostBack)
  • can contribute to anti-pattern of “tag soup”
  • code-block syntax and strong-typing can get in the way
  • IntelliSense enforces style not always appropriate for inline code blocks
  • can be noisy when designing simple templates
Example:
<%@ Control Inherits="System.Web.Mvc.ViewPage<IEnumerable<Product>>" %>
<% if(model.Any()) { %>
<ul>
    <% foreach(var p in model){%>
    <li><%=p.Name%></li>
    <%}%>
</ul>
<%}else{%>
    <p>No products available</p>
<%}%>
