The Domain Configuration File is typically used for any configurations associated with the domain, that need to be accessed at the time of service invocation. For example, the information required to access a database, or an input to the service, can be provided in the configuration file.

You must keep the domain configuration file in the same location as the assembly path. Also, enter only the name of the file. The domain configuration file is tightly associated with the particular domain. If you want to run the same service under the same domain with a different configuration file, you must first destroy the domain to remove association with the earlier configuration file. After destroying, recreate the domain, and associate another domain configuration file with the domain.

Ensure that the configuration file has a key named as WhitelistDirectories and that the white-listed directories are specified as value for the key. For more information on white-listed directories, see Specifying white-listed directories.
