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 'system.net/defaultproxy' configuration section"
How can i handle that ?
I had this same problem today and found a solution for it. In my case, the problem occurred because I was using a network disk for storing my project. When run from this network disk, this problem occurred. I moved the project to my local hard drive and it was gone. I am guessing this has something to do with security, as Windows considers the network drive less secure than my hard disk.
