Singleton vs. Monostate in C#: Understand the Difference with a Real-World Story and Code Examples

Learn the difference between Singleton and Monostate design patterns in C# through a simple real-world story. Discover when to use each, how they work, and see full code examples to help you write cleaner, more maintainable code. When designing applications in C#, we sometimes need to ensure that a class behaves in a global or shared way — whether that means only one instance exists, or that all instances share the same state. Two popular design patterns for this are the Singleton and the Monostate. They might seem similar at first, but they’re actually quite different under the hood. Let’s explore both using a story you’ll never forget.
