CLR Console application vs Win32 Console application

Jul 5th, 2008

I am using Visual Studio 2005.

Following two programs has the same code, just that one is CLR Console application and the other is Win32 Console application.

I set a break point at int i=1 for both program, for CLR Console application, and when run to the break point, in the local windows,
I have seen none of the value set for the array beans;but for Win32 Console application, the value has been set correctly.

What is the reason for this different?

Maybe its a compiler debugger bug -- I used VC++ 2008 Express and the CLR version displays the values the same way your link shows for the win32 console program.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

Hi Ancient Dragon,
I have updated my VS to Service Pack 1, now CLR Application Console looks normal again!
As you have mentioned, the problem may related to VS debugger itself.
Thanks

Very briefly, clr is managed, .NET, program. Win32 console is not.

ok i understand what you mean, can you do the same for windows forms development? can you write unmanaged windows forms development so that it can operate faster?

what makes you think managed code runs faster than unmanaged code? Faster is a relative word -- top speed is not an issue with programs that require human interaction.
