Calling .Net assembly from Biztalk Orchestration: Where to put Config

BizTalk uses its own configuration file called btsntsvc.exe.config which is in the BizTalk program files directory. You can add your configuration sections into this file and then bounce the biztalk host instances to pick up the changes.

HOWEVER, this is not good practice. It's OK to do this when you have only a single BizTalk app server but if you need to scale out suddenly you have multiple config files to maintain.

The recommended approach is to use SSO to store app-specific Config data, since it's BizTalk's Config storage solution and therefore always available. I always use this method and have never had any problems (although there is some overhead associated with development and management).
