Hi Aarif: Static class Vs Singleton pattern: The big difference between a singleton and a bunch of static methods is that singletons can implement interfaces (or derive from useful base classes, although that's less common, in my experience), so you can pass around the singleton as if it were "just another" implementation.

In singleton Pattern Your app should be instatiated only one oblect of the class.You can not define more objects from the class.So the return object method or property should be static.Bellow provide some examples https://www.c-sharpcorner.com/UploadFile/akkiraju/singleton-vs-static-classes/ https://www.dotnetperls.com/singleton-static

When to use staric and Singleton Static calsses are used when you have some helper method which is common and called from multiple places, you created static class with static method by passing required inpputs which returns an output from inputs. Singleton It is used to mostly in your program if you are using component like logging etc it is treated as global object on your full product and does not need to depend of any module, you create one singleton object for your whole program to use for logging purpose. Search Results from googling with definination. Featured snippet from the web Main differences are: Singleton has an instance/object while static class is a bunch of static methods. Singleton can be extended e.g. through an interface while static class can't be. ... Singleton object can be passed to methods while static class as it does not have instance can't be passed as parameters

What makes you say that either a singleton or a static method isn't thread-safe? Usually both should be implemented to be thread-safe. The big difference between a singleton and a bunch of static methods is that singletons can implement interfaces (or derive from useful base classes, although that's less common, in my experience), so you can pass around the singleton as if it were "just another" implementation.A singleton allows access to a single created instance - that instance (or rather, a reference to that instance) can be passed as a parameter to other methods, and treated as a normal object. A static class allows only static methods.

What is the different between singleton and static class? Singleton is a design pattern which solves the problem in a particular context (when we want that only one instance of an object can be created). Whereas static class is a concept where class will be defined with static keyword and all the members need to be strictly static. Singleton pattern let us create the object of the class only once whereas we can't create the object of static class. Class which follows singleton pattern can implement other interfaces whereas static class cannot.
