In July I tested the new 70-483 (Programming in C#) exam, pre-requisite to achieve the MCSD: Windows Store Apps Using C# certification*.* Today I've been told that I passed the exam.
Earlier this summer I also tested the new 70-484 (Essentials of developing Windows Store Apps), 70-485 (Advanced Windows Store Apps development) and 70-487 (Developing Windows Azure and Web Services) exams, still waiting for the results.
All the exams are now open to all developers, schedule yours in a Prometric Testing Center. For more information, visit the official Microsoft Learning website.
