It is a thread that executes in the .NET Framework and, at regular intervals, checks whether there is any unused memory in the application. If it does find memory, then it reclaims that memory and destroys the underlying object.

Suppose we have implemented a .NET web application in C#. Now, let's assume that during any interval of time, there are several people who are trying to access this .NET application. The following is one particular scenario that will give us an idea of why garbage collection is a very important part of C# or, for that matter, any .NET application:

  • When a user browses the application, they can execute a number of functionalities, such as accessing their profile or executing operations (for example,...
