Common Pattern in ASP.NET Razor For Clean cshtml Pages

I’ve been doing a lot of work over the past year in Microsoft’s ASP.NET Razor.  I’m not an html wizard and definitely a razor syntax wizard, but I have figured out a way that saves me time over and over.  It’s basically the same pattern of thinking that has me often do things in 2 or 3 steps instead of one just to make sure the logic is overly clear.

Just to be clear, below is what I’m talking about: What this does is to make sure that the trusted … Continue Reading
