Why is try / catch / finally not supported in C++ / CX?

Question

What happened to try / catch / finally???

   try
   {
      // call something that might throw an exception
   }
   catch (Exception ^ ex) // must have catch, otherwise error: C2317
   {
      throw ex; // just re-throw b/c I didn't want to catch it in the first place
   }
   finally // Error: C2065
   {
      // do cleanup here
   }

Seems like another big step backwards for C++ / CX and WinRT.

Answer 1

In C++ you don't need finally block, just use RAII pattern

Answer 2

Doesn't answer my question.  I have hundreds of thousands of lines of C++ / CLI code that I am trying to port, maintain, support.  By not having this feature, it is like I said, and big step backwards.

Answer 3

not sure if this is lame or not:
