Today, I passed the test for the exam 70-486 Developing ASP.NET MVC 4 Web Applications. There are tons of guides/links that helps you to prepare for this Exam e.g.:
In addition I would like to mention the Youtube-Channel of Kudvenkat.
I also recommend his ASP.NET Tutorials if you need some background information (e.g. OutputCache).
- ASP.NET Basics (Scott Hanselman)
- MVA (MVC)
- RoleProvider / MembershipProvider
- Windows Azure Worker Roles
- RDP + Azure
- Azure Startup Tasks
- Contracts Library
Hope this helps.
