How many applications can I sideload to Windows 10 Mobile? Thank You.
As for the latest build, you can sideload n number of applications. There's no limit.
If you want to sideload/deploy apps to your phone, use 8.1sdk or xap deployer 2.0 or wppt on pc to do it. Also assure you install ipoverusb in pc sothat app deployment over usb is possible! 8.1sdk works with win 8 and 8.1pc but xap deployer 2.0 and wppt needs win 10 with 8.0sdk installed.
