Hi Martijn,

Good to know. I was wondering what the reason is that an Isolated Host needs a new app pool. The Technet article just says "You must create at least one application pool for each isolated host.", but I can't find the reason why. I understand that an Isolated Host instance can only run one adapter and that consequently an Isolated Host running multiple adapters needs one app pool per adapter, but I can't understand why two Isolated Host instances can't use the same app pool if they run the same adapter. Do you know why?

Hi Martijn ;-),

Basically, adding another application pool creates a separate process for the host to live in. Otherwise, it would be two hosts within the same process, which defeats the purpose ;-)
