I receive the error from a third party application exe. The Application is only a exe, no config file or others.
\"error creating the web proxy specified in the \'sy
I had the same problem with one of my apps. On TEST server everything was ok, on PROD server the app was failing with this error message.
Turns out that case in important! On my TEST server, the config file had => working.
On my PROD server, I had the same setting => not working. I changed that to , with a capital 'P', and everything is fine now. I guess the framework version is not the same between my servers, and one forgives more spelling errors.
Edit: actually my PROD section was all lowercase. I probably messed up when editing the config file, and typed a keyboard shortcut to convert my file to lowercase...
