How can I find xmlconfiguration files that I import from Web?

I have Imported several xml files that I got from the web from which c# sharp code was automatically generated. However when I run the scene any reference to said files file gets this error, : " invalidOperationException: Client endpoint configuration '*' was not found in 0 endpoints." Now I know how to fix this problem but I cannot for the life of me find the configuration file. When I successfully imported the dll unity made a service reference folder with the generated code and some xml files. however I was not able to find the correct config xml in this folder. Where can I find the location of an imported dll config file?
