Is there any difference between `new object()` and `new {}` in c#?

Question

in c#,

var x = new {};

declares an anonymous type with no properties. Is this any different from

var x = new object();

?

Answer 1

Yes, the types used are different. You can tell this at compile-time:

var x = new {};
// Won't compile - no implicit conversion from object to the anonymous type
x = new object(); 

If you're asking whether new{} is ever useful - well, that's a different matter... I can't immediately think of any sensible uses for it.
