The factory method is a generating design pattern that allows you to carry its instance creation into a separate class. That is, the base class defines the creation interface, and the implementation of the creation process is performed by the heirs.
We will look at the idea of this design pattern in detail and implement it in the C # programming language. And also consider the advantages and disadvantages of the design pattern factory method.

Design patterns describe typical ways to solve common software architecture problems. Design patterns are not a specific code, but a general concept for solving a particular problem, which will still need to be tailored to the needs of your program. The generating patterns solve the problem of creating new class instances.
We implement the factory C # method (factory method c #) or, as it is, sometimes also called the virtual constructor using the example of several popular instant messengers with the ability to send messages of various types. Such C # design patterns (design pattern c #) allow you to save the class from being tied to specific products. The factory method pattern makes it easy to add new products to the program. Design Patterns C # implements the principle of openness / closeness. But it is important to remember that the factory method pattern can lead to the creation of a large number of parallel class hierarchies. C # templates (C # templates) should be used with caution and not implemented in places where they are not needed.

By the way, my name is Shvanov Vadim, and I am a professional .NET developer with over 8 years experience and the author of this channel CODE BLOG. I talk about IT technology and lead this course on the C # language from scratch. Within its framework, we will consider both the basic syntax of the C Sharp language, and its practical application and special technologies, such as ASP .NET, Core, MVC, Unity, WCF, WPF, data structures and algorithms, design patterns, computer science, software and much more. For me, it is important not only to show the practical application of the C # language, but also to explain the basic idea and basic concepts of Computer Science. Visual studio c # and visual c # projects are used as the main development tool.
