Why should you care?

ShopNest-style stories beat textbook definitions when you interview for .NET roles.

See it live — copy this example

Paste into a C# console or class library project and run dotnet run.

// Answer template
Console.WriteLine("1) Problem in ShopNest");
Console.WriteLine("2) Pattern name + structure");
Console.WriteLine("3) Tiny C# sketch");
Console.WriteLine("4) Trade-off / when NOT to use");

What happened?

• Lead with the pain, then the pattern.
• Show you know limits.
• Prefer Strategy/Repository/Observer stories you actually lived.

Practice next

1. Pick three patterns and rehearse ShopNest stories.
2. Draw Strategy vs Template Method difference.
3. Practice “when not to use Singleton”.
4. Time a 3-minute Strategy answer.
5. Compare Decorator vs Proxy aloud.

Remember

Problem → pattern → trade-off. Real examples win. Know when not to use.
