Hello Gak,

Regarding on the programming for 64 bit platform through Visual Studio 2005
, do you concern .net framework based application or unmanaged application?

For .net framework application, when installing the .net framework, you can
choose to use 64 bit .net framework. And when installing visual studio
2005, it will automatically install 64 bit framework (according to the
underlying platform). Thus, when you develop .net framework application on
that machine in Visual Studio, the compiled program will reference the 64
bit framework libraries.

for unmanaged application developing, you can refer to the following msdn
reference:
