The Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation exam is the official Microsoft assessment behind the Microsoft Certified Technology Specialist (MCTS) credential, which sits at the Professional level. Passing it confirms that your skills meet the vendor's current requirements rather than a textbook outline. It also connects with related certifications such as MCTS: .NET Framework 3.5, so it can anchor a broader certification path.
According to the official exam information, the Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation exam includes Approximately 40–60 questions and gives you 120 minutes to complete them. Treat that as a pacing exercise, not just a knowledge check: bank the questions you know first, flag the ones that stall you, and circle back instead of burning minutes on a single item. Before test day, run at least one full timed session in the Actual4Cert desktop or online test engine, so the clock never feels unfamiliar when it counts.
To pass the Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation exam you need 700 (on a scale of 1000), and the official registration fee is USD 125 (varies by region). Keep one thing in mind: a failed attempt is not discounted, so retaking the exam means paying USD 125 (varies by region) again in full. A practical safeguard is to sit a complete Actual4Cert practice test a week or two before your exam date; if your timed scores are not sitting comfortably above the passing mark, consider pushing your booking back and drilling the weak domains first.
