Debugging is the core part of any application development. It is a process that helps you to quickly look at the current state of your program by walking through the code line by line. Developers generally start debugging the application while writing code. Some developers start debugging even before writing the first line of code to know the logic and functionalities. It's a rare case scenario when a developer completes writing code without debugging the application.

Visual Studio provides us details about the running program as much as possible. It also helps to change some values while the application is already running. Thus, debugging inside Visual Studio IDE is becoming more popular day by day.
