Compile Asp.NET to 32 bit on 64 bit system

I've seen in several places that this can be set in the build options for my project. However when I go to the Property Pages -> Build for my project, it does not have an option for target platform. When I go to my开发者_开发问答 solution, most projects have x86 as an option, but the web project only has Any CPU.

How do I force the web page to build to 32 bit?

Go to Build -> Configuration Manager, select the drop down in the platform column, select new, select x86.

Go to Solution level NOT Project level and follow the selection / editing suggestions above.

The only way I got this to change was to go in to the .sln file with a text editor and directly hack in the values I needed (which worked).
