C# and .NET Application Development

Build practical C# and .NET applications using object-oriented programming, databases, authentication, and application logic. Progress from C# fundamentals to complete desktop and database-driven projects built with real development techniques. In this Specialization, you will develop practical C# programming skills while learning how core concepts work together in functional applications. You will create reusable functions, work with data structures and parameter passing, and apply encapsulation, inheritance, and polymorphism to build maintainable object-oriented software. You will then develop Windows Forms and login-based applications, manage files with C# IO classes, validate user input, and handle runtime and file-related exceptions. As your skills progress, you will use ADO.NET to connect applications to databases, retrieve and filter records, implement authentication, and perform CRUD operations. Through hands-on projects, you will apply these skills to database applications, desktop games, a rule-based chatbot, and an online examination system. By the end, you will be able to combine C#, .NET, object-oriented design, databases, and application logic to develop structured, practical software solutions.
