The Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation (exam code 070-503) is the exam you pass to earn the MCTS certification, a credential at the Technology Specialist level. It is also connected with related credentials such as Microsoft Certified Technology Specialist .NET Framework 3.5, 70-505 TS: .NET Framework 3.5 Windows Forms Application Development, 70-502 TS: .NET Framework 3.5 Windows Presentation Foundation Application Development, 70-561 TS: .NET Framework 3.5 ADO.NET Application Development. If you are mapping out a certification path with Microsoft, this exam is a milestone worth planning around.

The 070-503 exam includes 40-60 questions, and you have 120 minutes to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the 2Pass4sure test engine under the same time limit, so the pace feels familiar rather than frantic on the day.

You need 700 (on a 1000 scale) to pass the 070-503 exam, and the official registration fee is USD 150. That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the 2Pass4sure practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.

Experience developing distributed applications using Microsoft .NET Framework 3.5 and Visual Studio.
