**Object Initializer** — Curly braces after `new` that set an object's properties in the same statement that creates it, instead of one assignment per line afterward.

```csharp
Book book = new Book { Title = "Dune", Pages = 412 };
Console.WriteLine(book.Title); // Dune

class Book
{
    public string Title { get; set; } = "";
    public int Pages { get; set; }
}
```
