by Dan Wahlin

What's new in Visual Studio 2012 and ASP.NET 4.5 for web developers.

What you'll learn

This course provides a tour of what's new in Visual Studio 2012 for ASP.NET Web Forms developers and how it can make you more productive as a developer. The course begins by showing you key enhancements to Visual Studio's HTML editor and its improved support for working with CSS and JavaScript. Next, you’ll explore what's new with data binding (some significant features have been added here) including model binding and strongly typed data controls. You’ll also see enhancements that have been made to the ASP.NET framework such as bundling and minification of JavaScript and CSS, asynchronous modules and handlers, SignalR and more. Several new HTML5 features are also demonstrated including new HTML5 input types, Web Sockets and support for multiple file uploads. The course concludes with a look at important security-related improvements in ASP.NET including support for OAuth, request validation and support for preventing cross-site request forgery (XSRF) attacks.
