"Upload requires a serial port or programmer" Error?

I'm re-asking this question because it took me over a week to respond to my original topic thus resulting in its abandonment. My fault, sorry!  Undecided 

Anyway, I am using the arduino visual studio plugin. 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 also made sure the correct board type was selected. I looked through the options under the tools tab but honestly didn't know what I was looking at and got a little overwhelmed.

Clicking on the empty drop down box brings up an empty list, where I'm told there's supposed to be a list of ports. But there's frustratingly nothing. 

What am I doing wrong?  Huh

Thanks!

Sorry for the delay and thanks for the info. Another user reported this issue.

Visual micro uses c# instead of java to ask windows for a list of serial ports and it appear to be failing to do so.

You could try to switch off the following 3 "Tools>options>visual micro>communications" 
networkDiscovery
friendlyPortLists
friendlyPortMenus

If that fails try changing the com port number in "control panel>device manager" by right clicking the com port and clicking "properties"

So!

I switched off networkDiscovery, friendlyPortLists and friendlyPortLists in the options menu where you said. Doing so now adds COM4 to the drop-down list when the arduino is plugged in, however clicking on it doesn't slect it (the box the list drops down from remains blank) and I still get the "upload requires a serial port or programmer. Upload cancelled" error.  Undecided

Just so I can make sure that I know how to upload to the arduino with the IDE, I'm supposed to write my program, debug it, plug the board into the chosen USB port, click the build and upload button which looks like a play button in a circle, then sit back and profit, right?

Hi,

You are doing the right things. The serial port list should show the port.

This means that visual micro can't see the port hence the error during upload.

Can you please give the usb driver details for the port from device manager. Name, manufacturer, version, date etc.

Thanks very much

Short term workaround: You can switch on "File>Preference>External Editor" in the arduino ide. This allows you to have the same sketch open in visual studio and the arduino ide at the same time. You can edit/save in Visual Studio then click Arduino Ide Upload.

I am going to sound so dumb but how can I tell which driver I'm using from the control panel? 

I'm looking at the USB controllers and I'm seing well more than the four that I have on my computer.

Not at all. It's a good question. Why are your COM ports missing from device manager? Normally they are shown in a tree branch somewhere above the Universal Bus Controller that you have expanded.

It might be an idea to post a screen shot of your entire device manager with Universal bus collapsed.

Which version of windows are you using?

Are com ports set to "auto detect" in the BIOS?

Here is my device manager with the USB controller branch closed. 

I'm using windows 10, and where would I find the BIOS settings?

You should be seeing a com ports section. Please see if they are hidden and disabled.
