Spread in object literals

[Abdalla-Sleman]

Copying and merging objects :

example in javaScript you can do somthing like this :

const obj1 = { foo: "bar", x: 42 };
const obj2 = { bar: "baz", y: 13 };

const mergedObj = { ...obj1, ...obj2 };
// { foo: "bar", x: 42, bar: "baz", y: 13 }

How would this work in C# where types must be defined up front?

It could be exclusively for anonymous objects, but I'm guessing that's not what he wants
