Creational Design Patterns in Modern C++ - Application Framework - Implementation

The video tutorial introduces a framework for solving real-world problems by creating a new project. It covers adding document and application classes with virtual functions, implementing a text document class, and executing the application through a main function. The tutorial highlights the issue of tight coupling between the application and text document classes and suggests using a factory method to allow the application to work with any user-defined document class. The video concludes with a promise to explore the factory method implementation in the next video.
