c# - mdbg can't debug my hello world program -

in order try out mdbg, have following simple hello world program:

 // kkk.cs using system;  class hellomain {     static public void main()     {         console.writeline("hello");     } }

compile csc /debug kkk.cs, yields:

 kkk.exe kkk.pdb

i (from visual studio command line):

mdbg kkk.exe

mdbg !r kkk.exe

i got:

error: request not supported. (exception hresult: 0x80070032)

try csc /debug /platform:x86 kkk.cs

you're running on 64-bit windows. mdbg 32-bit process , can debug 32-bit processes.
