Global Instance Coordination

The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. This is useful for managing shared state like application settings.

snippet.cs

csharp

public class ConfigurationManager
{
    // A static property that holds the single instance
    public static ConfigurationManager Instance { get; } = new ConfigurationManager();
 
    // Private constructor prevents other classes from creating new instances
    private ConfigurationManager() { }
 
    public string AppName = "MyCSharpApp";
}

Breakdown

public static ConfigurationManager Instance { get; } = new ConfigurationManager();

Creates the one and only instance of this class.

private ConfigurationManager() { }

Prevents instantiation from outside the class via the 'new' keyword.
