Answer 1

If your application references 32-bit .dll-files it can't run as 64-bit. Either .Net assemblies compiled to x86-target (which is default now), or P/Invoke on native Windows .dll-files, will prevent you from running your 64-bit app.

The Windows installation you are running this on also needs to be 64-bit in order for it to handle 64-bit debugging. (Note: Compiling to 64-bit will work fine!)

Set target CPU type to x86 in project properties (under Build) to make it work. If you don't reference any external 32-bit .dll's you can set it to "any" to let .Net decide. It will then run 64-bit mode on 64-bit operating systems and 32-bit mode on 32-bit operating systems.

我不确定VS2010，但对于VS2005，我使用“混合平台”为“主动解决方案平台”设置。
