Compile for x64 with Visual Studio?

Question

Question: Assume a C++ hello world program, non .NET. With Visual Studio 2005/2008/2010, how can I compile a 64-Bit application ? I have a 64 Bit Windows, but by default, VS seems to compile 32 bit executables...

On Linux with g++, I can use -m32 and -m64, but how can I compile a 64 bit solution with Windows ? Is it even possible with 2005 ? Or does one need 2008 or even 2010 Beta, or even some x64 SDK ?
