I need to run Visual Studio on my MacBook Pro and I need Windows to do that. The easiest and well known way to install Windows on a Mac is by running the Boot Camp app on the Mac and let it do what's necessary. The problem is that I don't want to partition the Internal SSD so the remaining option is to install Boot Camp Windows 10 on an External Drive and boot it every time I need it by plugging in my external USB 3.0 HDD. Is this achievable?

Here's an updated procedure for Windows 10, based on orkoden's excellent answer.
I tested this process on a MacBookPro11,1 running OS X 10.11.5 (15F34). Throughout the process, directly connect all devices to your Mac. I found that certain operations failed more frequently if I used the USB hub in my monitor.
In addition to the external drive that will host your Windows installation (the "destination drive"), you will need another USB drive (the "driver drive") to temporarily store the Boot Camp drivers.
I used these parts:
Here are the steps:
diskpart
list disk
to determine the disk number of the destination drive. In my case, the disk number was 1.select disk 1
clean
create partition primary
format fs=ntfs quick
assign
active
list volume
exit
imagex /check /verify /apply d:\sources\install.wim "Windows 10 Home" e:
"Windows 10 Pro"
"Windows 10 Education Retail Technical Preview"
bcdboot e:\windows /v /s e:
shutdown /p
Windows is now installed and ready.
