SOAP Client: System.InvalidOperationException

Question

When I run a windows service which is trying to send XML data via SOAP, I am getting this error. Note, this is converted over from a C++ version. I know svcutil is used to generate the C++ code based on other files. I haven't been able to figure out if I'm missing a reference.

Application: ENS_Service.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Error is occurring when loading the configuration. Several thoughts here:

• Does this code work when run locally as a console app?
• Do you have the configuration file for the service set up to work with your client settings?
• There is likely an inner exception occurring here that has the details. Dump the root exception + any InnerException values.

If the code works as a console app but not as a service then it is almost always a permission issue. Services don't normally have network access. But I'm not sure that is the problem here.
