Just got the Visual Studio 11 developer preview installed. I see a new option in the project properties called “Prefer 32-bit” when compiling a managed (C#, VB) application with the AnyCPU target specified. This doesn’t appear to be an option for class libraries, just top-level apps.
What does this flag indicate?
It likely indicates the app is AnyCpu but when 32 bit is available it shouold run as such. This makes sense – 64 bit apps use more memory, and sometimes you just dont need the memory space 😉
