The 70-355 exam is the official Microsoft exam for Microsoft Universal Windows Platform - App Data - Services - and Coding Patters. Passing it earns you the Microsoft Certification credential, which sits at the Professional (historical) level. It is also connected to MCSD: Universal Windows Platform, so what you learn carries over if you plan to pursue those paths as well. Employers treat the certification as verified proof of skill, which is why structured preparation with 2Pass4sure's practice questions pays off.

Candidates should have 1+ years of experience developing with C# and XAML and implementing enterprise UWP apps; experience with LOB apps, services and maintainable coding practices is recommended. :contentReference[oaicite:0]{index=0} Eligibility details can change, so before you register, confirm the current requirements on the official exam page: https://learn.microsoft.com/.
