Because multiple endpoints of the Protocol are configured. Follow the name to indicate the preferred endpoint configuration section.

After adding a service reference to vs 2008, if you "Update" the service reference, or "delete" the service reference and add it again, this error will occur during running. This is because when the "update/Delete" service is referenced, the app. the config file is not automatically modified. After "Update" or "add" again, two identical "endpoints" will be generated. You need to manually delete the original endpoint to run properly.
