On subsequent runs, it returns the client On the first run, it creates a singleton object and places This is the static method that controls the access to the singleton which, however, doesn't work really well in multithreaded program. In this example we'll show the simplest of these ways, multiple ways to initialize this field, all of them have various pros The Singleton's instance is stored in a static field. direct construction calls with the `new` operator. The Singleton's constructor should always be private to prevent inheritance through external classes and also through nested classes. EN : The Singleton should always be a 'sealed' class to prevent class alternative to constructor and lets clients access the same instance of The Singleton class defines the `GetInstance` method that serves as an Program.cs: Conceptual example using System Multiple threads can call the creation method simultaneously and get several instances of Singleton class. The same class behaves incorrectly in a multithreaded environment. You just need to hide the constructor and implement a static creation method. It’s pretty easy to implement a sloppy Singleton.
