Adding a new BizTalk Server Isolated Host needs a new Application Pool

Recently, we tried creating a secondary Isolated Host to separate receive and send processing for WCF. After reconfiguring the servers, we were faced with the "Receive location for address '' not found. (The BizTalk receive location may be disabled)". Puzzled, we looked around for configuration issues. After some reading (https://technet.microsoft.com/en-us/library/aa559328.aspx), we remembered a new isolated host needs a new application pool. Adding another application pool to the mix the the new host fixed our trouble...

Jotted down for posterity ;-)

  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 ;-)
