This is purely out of curiosity.

In C and C++, the following statements invoke undefined behavior:

int i = 3;
i = i++;

(for reference:
http://www.eskimo.com/~scs/C-faq/q3.3.html )

Does the C# standard specify the behavior for such constructs? A quick test
reveals that the value assigned to i is 3 which is interesting, but not
particularly revealing.

It's fairly simple in C#. The RHS is evaluated and has a value of 3
while incrementing i to 4. The assignment is then performed, setting
the value of i back to 3.
