Razor Helpers Syntax One hidden gem of Razor View Engine is the declarative helper syntax. With this syntax we can create helper components that are stored as .cshtml files, and enable reusability of view code. The name of the syntax might sound familiar and it is since it reminds the HtmlHelper class that was provided as part of MVC 1.

ASP.NET MVC Model Binders One thing that I’m always asked to talk about when I’m delivering ASP.NET MVC sessions or courses is Model Binders.

Instead he had an empty database for his disposal in the hosting environment without a way to run SQL scripts… In such a situation the provided...
