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 ;-)
