Actually it is. The very same error will be generated if you are trying to load x64 assmebly under x86 CLR or vise versa. This can happen if you didn't build your managed assembly with "AnyCPU" target.
Also as the message indicates it can be a dependency problem. But this one can be easily ruled out by testing it with any of the unmodified ManagedCustolmActions samples.
