AddressAlreadyInUseException when starting azure project locally
It helped me to shutdown both Computing and Storage Emulator, close Azure Simulation Monitor (csmonitor.exe systray application) and manually start the Azure Emulator as an administrator. Also if it started the Emulator Express and you need Full Emulator (I expect so, since this error didn't appear with the Express for me), just stop it and start the Full Emulator using systray icon.
Just don't let Visual Studio to start it automatically. I don't know what was the real reason of that error, but this solved it for me.
