Is there any difference between new int[0] and new int[]{}

Question

I want to inizialize a new int array.

What are the advantages of:

var myNewArray = new int[]{};

And:

var myNewArray = new int[0];

Which one should I prefer over the other, or is it just a matter of code-style?

@Bartosz thanks for the link. However, this is about initializing an array with items. I specifically wan't an empty array. — Mafii, May 18 '17 at 08:07
No difference. But starting with NET4.6, the preferred way is to use [`Array.Empty()`](https://msdn.microsoft.com/en-us/library/dn906179(v=vs.110).aspx) which returns a singleton instance. — Ivan Stoev, May 18 '17 at 08:11
@IvanStoev thanks a lot! I knew of Enumerable.Empty but somehow overlooked Array.Empty. — Mafii, May 18 '17 at 08:12

There is no difference. Both produce the same IL:

IL_0000:  nop         
IL_0001:  ldc.i4.0    
IL_0002:  newarr      System.Int32
IL_0007:  stloc.0     // myNewArray
IL_0008:  ret
