Is this needed, @shargon?

The compiler is going to be different.
Maybe we can just say that the syscall is not valid. I think there is not need to really explicit that it is NEO2.

@vncoelho Hey, my friend, since we've not deployed a new nuget for NEO3 SmartContract Framework, and the NEO3 one is also using the version number 2.9.3, it can make developers greatly confused, including me, hahaha. So I think this error message is necessary because if you're using the NEO2 nuget of Framework 2.9.3 to deploy a sc on NEO3, it's incompatible.

Yes, If you use the old version of SmartContract.Framework, you can get a wrong NEF, so I think that this checks could be very useful. Is possible that some invalid contract pass, it is a basic filter for prevent some human errors.
