So I'm using Visual Basic C++ 2010 to right my Visual Hello World project for school. I've gotten the code written but I keep getting 'LINK : fatal error LNK1561: entry point must be defined'.
I've looked under
Properties -> Linker -> System >
for the Configuration and it's blank. This is my code. Can you point it out on where I need to define my entry point?
