Duration 5 Days – 35 hrs.
Overview
The Advanced C# Programming with Secure Coding Training Course is an intensive hands-on program designed for software developers who want to strengthen their expertise in advanced C# programming while incorporating secure coding principles throughout the software development lifecycle. The course covers advanced object-oriented programming, asynchronous programming, design patterns, performance optimization, modern .NET development techniques, and secure software engineering practices aligned with industry standards such as the OWASP Top 10 and Microsoft Secure Coding Guidelines.
Participants will learn how to develop secure, scalable, maintainable, and high-performance applications by applying defensive programming techniques, input validation, authentication and authorization mechanisms, secure data handling, cryptography fundamentals, and secure API development. Through practical coding exercises and real-world scenarios, participants will gain the skills required to build enterprise-grade .NET applications with security integrated by design.
