This course is a lecture that teaches C# Windows Forms (WinForm) application development step by step from basics to hands-on practice. First, you will understand how Windows Forms applications work and learn the structure and usage of WinForm classes and Application classes. Through this, you will become familiar with the execution flow of applications and build a foundation through actual code practice. In the following lessons, you will design forms using the form designer tool and implement **user interfaces (UI) utilizing various controls** such as buttons, text boxes, and labels. Rather than stopping at simple UI composition, you will develop the ability to create programs applicable in real work by adding event handling and interactive features. Additionally, you will practice asynchronous task processing methods in the WinForm environment and learn techniques to simultaneously improve application performance and user experience. Through this course, learners can solidly build the fundamentals of desktop application development in Windows environments and acquire WinForm programming capabilities applicable to real work.

This course is a step-by-step learning program that covers network programming from fundamentals to hands-on practice. First, we examine the origins and development of the Internet to understand how today's network environment was formed. Next, we learn the structure and operating principles of the TCP/IP protocol, which is the core of networking, to build a theoretical foundation. In the practical stage, we implement actual network communication using the Socket class, TcpListener, and TcpClient classes provided by C#, and experience client-server architecture. Through this, you can understand the actual data transmission and reception process and network connection procedures beyond simple theory. Finally, we visually implement network programs by creating user interfaces (UI) using WinForm. We practice enabling connection, message transmission, and reception through button clicks, developing the ability to create network application programs that can be utilized in real-world environments.
