This five-day course provides an end-to-end learning journey through the C# programming language, from the fundamentals of procedural coding to advanced object-oriented techniques and data handling. Designed to prepare developers for creating robust, maintainable applications in the .NET Framework and .NET Core, the programme covers console applications, class libraries, unit testing, and database-first development using Entity Framework. Learners start with the essential syntax, structures, and object-oriented principles before progressing into inheritance, interfaces, delegates, LINQ, and exception handling. The course blends lectures, demonstrations, and hands-on exercises, ensuring participants gain practical experience at every stage. By the end of the week, learners will be ready to apply their skills to professional .NET development projects.
