Creational design patterns in C# focus on the process of object creation, providing flexibility and decoupling the system from the specific classes it needs to instantiate. Let's discuss some common creational design patterns along with examples in C#: 1.      Singleton Pattern : Ensures a class has only one instance and provides a global point of access to it. 2.      Factory Method Pattern : Defines an interface for creating an object but leaves the choice of its type to the subclasses, creating instances of multiple classes. 3.      Abstract Factory Pattern : Provides an interface for creating families of related or dependent objects without specifying their concrete classes. 4.      Builder Pattern : Separates the construction of a complex object from its representation, allowing the same construction process to create different representations. 5.      Prototype Pattern ...

The   Singleton Pattern   ensures that a class has only one instance in the across application and the object instance coordinates across the app. This pattern is the simplest design pattern and is used to restrict the creation of multiple object instances. This pattern is the simplest design pattern and is used to restrict the creation of multiple object instances. A class should have the following structure for the Singleton Design Pattern: 1.       Should have a private or protected constructor. No public and parameterized constructors. 2.       Should have a static property to return an instance of a class. 3.       At least have one non-static public method for a singleton operation. The Singleton pattern is often used for: 1.        Logging 2.        Database connections 3.        Caching 4.  ...
