On a 32-bit machine:
Any CPU: runs as a 32-bit process, can load Any CPU and x86 assemblies, will get
BadImageFormatException
if it tries to load an x64 assembly.x86: same as Any CPU.
x64:
BadImageFormatException
always.
On a 64-bit machine:
Any CPU: runs as a 64-bit process, can load Any CPU and x64 assemblies, will get
BadImageFormatException
if it tries to load an x86 assembly.x86: runs as a 32-bit process, can load Any CPU and x86 assemblies, will get
BadImageFormatException
if it tries to load an x64 assembly.x64: same as Any CPU.
It is the JIT compiler that generates an assembly code that's compatible with the requested target based on this flag.
