Hi, I am using visual studio to write an Arduino program with the arduino extension. It builds just fine with no errors but when I go to upload to my Mega 2650 I get the error "Upload requires a serial port or programmer. Upload cancelled."
I've used the actual Arduino IDE before and uploaded to Arduino boards with no issue on the same laptop.
Thus far I have tried all four USB ports on my labtop and recieved the error. I looked through the options under the tools tab but honestly didn't know what I was looking at and got a little overwhelmed 
How do I resolve this or at least go about figuring out how? Thanks!
