I read ScottGu’s explanation on Strongly Typed Html Helpers and I understand that it gives me the ability to do better compile time checking of views. I was under the impression that I already had this when I used the model.PropertyName in the MVC1 Html.TextBox helper, but apparently that is not true. So, how does using a lambda expression do this better for me?

    Consider the syntax of the existing HTML helper methods:

    <%= Html.TextBox("Quantity", Model.Quantity) %>

    If you rename the Quantity property on your object to “CurrentQuantity”, the generated <input> element will still have name="Quantity" specified, and model binding will break if you don’t remember to change that first parameter.

    By using a lambda expression to specify the name of the element, an incorrect or misspelled property name becomes a compilation error. 

    <!-- No magic strings here! -->
<%= Html.TextBoxFor(model => model.CurrentQuantity) %>
