Hi Friends,

I have an ASP.NET 2.0 32 bit application. In the VS 2005 solution, there are
3 class library projects and 1 web site/web project. I changed the target
environment to x64 and complied the class library to 64 bit. I cross
verified with CORFLAGS and the dlls are PE32+. When I compile or publish the
web site/web project which references the 64 bit dlls, I get the following
error:

"Could not load file or assembly 'Name' or one of its dependencies. An
attempt was made to load a program with an incorrect format."

1. How can I compile the entire solution in 64 bit?
2. What if I deploy the 32 bit compilation on a 64 bit environment (Win 2k8
R2), will it run in 64 bit by default?
3. Can I change the ASP.NET mode in IIS to only run in 64 bit?
4. I am using the Publish option to pre-compile the entire web site before
deploying.

In a nut shell, I want to run my 32 bit app (managed code) in true 64 bit
environment (no WOW).

Kindly assist as its very urgent.

Regards
Amit
